UPDATED: Normal friction blisters are full of clear fluid. Blood blisters have blood mixed in with the normal blister fluid. They look red at first, and then go a darker purple/black colour as they dry. It pays to have a healthy respect for blood blisters on feet as they pose a heightened risk for infection.

Do you know why blood blisters form? How to deal with them? Do you pop them or not? And how long will they take to heal?

Summary

Blood Blister Do’s

  1. Do apply an antiseptic – just in case it pops
  2. Do protect it with a sterile island dressing – like a bandaid
  3. Do get the pressure off it (or at least reduce it) and reduce friction levels – otherwise it will get worse

Blood Blister Don’ts

  1. Don’t just ignore it and keep going – it will very likely tear and open itself up to infection
  2. Don’t ignore the benefits of popping it – but only if the situation is right! (more on that in a moment)
  3. Don’t neglect pressure relief and friction relief – otherwise it will get worse

 

FAQs About Blood Blisters

1. What Can Cause Them?

The presence of blood in a blister indicates there is high pressure component. It’s this high pressure that causes deeper injury compared to normal blisters. When there is injury to small blood vessels in the dermis, blood is able to leak into the epidermis and mixes with the normal blister fluid. That’s why blood blisters often occur over joints and bony prominences: like the bony bit at the back of the heel, the toes and the metatarsal heads (ball of the foot).

blister skin layers

Blood vessels exist in the dermis, not the epidermis where blisters form. That’s why normal blisters are not filled with blood.

2. What Colour Are Blood Blisters Meant To Be?

In the initial stages, a blood blister looks red. Then as the blood dries and coagulates over time, is goes a purple or black. You can read more about the colours of blisters here.

Caution: If you notice a black spot on your foot, be mindful there are other potential diagnoses other than a blood blister. Of highest importance would be melanoma. If there has been no trauma to have caused a blood blister, please consult your doctor to rule out melanoma.

 

3. How Long Do Blood Blisters on Feet Take to Disappear?

We know it takes somewhere from 30 to 48 days for full epidermal cell turnover – that is for cells to travel from their deepest to most superfical, to be shed as dead skin cells. It took 6 weeks in this case study. So that’s how long it will take for the discolouration to disappear.  The blood will dry relatively quickly, assuming you take away the cause (remember to reduce pressure and friction levels). If you don’t deal with the cause, your blood blister will recur and the whole process will take longer. 

As the damaged skin and dry blood works its way to the surface, you may find a lot of black dried blood that flakes away. Or there may be just a little – it will depend on these things:

  • How big your blister was
  • How much of the fluid was reabsorbed
  • And how effectively you were able to deal with the cause

Blood Blister Causes

Structural Causes

Bony prominences are at most risk, like a bunion for example. Your forefoot is wider when you have a bunion. However, it’s not necessarily the bunion protuberance itself at most risk of developing a blood blister. It’s the weightbearing undersurface that’s at risk. There’s a concentration of pressure as the prominent joint bulges over the sole of the shoe. Coupled with high friction, there’s a blood blister waiting to happen.

Biomechanical Causes

The blood blisters under the big toes in the first image of this article are a consequence of the foot’s biomechanics. There’s an important function of the 1st MPJ (big toe knuckle) called the windlass mechanism. When it’s not working adequately, there can be extremely high pressure under the joint of the big toe – where these blisters are.

peak pressure under foot

Functional hallux limitus (inefficient windlass mechanism) as a cause of blood blisters under the big toe.

The best way to deal with this is with to see a Podiatrist because they know how to facilitate the windlass mechanism – treatment will likely include orthotics and calf stretches and maybe some other things, depending on where you’re getting blood blisters.

Really, the best way to get on top of any recurring blood blister that you don’t know the cause of, is to see a podiatrist. We know a lot about foot structure and functions and the best ways to reduce pressure points and friction levels.

 

What Do You Do With a Blood Blister On Your Foot?

If you miss the blister prevention boat and end up with a blood blister, follow the normal blister treatment sequence to get rid of that foot blisters. But now, preventing infection really is your priority! As a result, consider the options below, depending on your blister location, the environment you’re in and what gear you have access to. 

Blood Blister Treatment Should Include:

a) Take Away All Pressure

If it’s possible, remove all pressure to ensure the blister roof remains intact and allow it to heal in its own time. For example, a blood blister on top of your toe would benefit from simply wearing open-toed sandals. Similarly, a blister at the back of your heel would get relief from wearing open-backed scuffs. However, if your blister is under your foot, or you simply must wear enclosed shoes, it’s impossible to negate all pressure.

b) Reduce Some Pressure AND Reduce Friction Levels

This is where pressure deflection can help in conjunction with reducing friction levels on and around the blister. They are called friction blisters, after all! Here’s How:

  • Reduce pressure with donut pads cut from thick adhesive orthopedic felt. The idea is you place the cavity over your blood blister to keep the pressure off it.
  • Reduce friction levels with Engo Blister Patches. You stick these to your shoe or insole to stop the skin stretching (shearing) and tearing the capillaries further.

Are You Supposed To Pop A Blood Blister On Your Foot, Or Not?

There are times when keeping the blister roof intact is not the best option. It can be better to take matters into your own hands rather than ignore it and simply hope for the best. If you have the right equipment, you could deal with this appropriately and safely. It sure beats putting your blood blister with roof intact back into your shoe with no dressing and no pressure relief, therefore just leaving it to chance. 

However, please realise the risk of bacterial infection when you open up a blister. For the following few days, you’ll need to be on the watch for signs of blister infection which include redness, swelling, pain and pus. Moreover, if you notice red streaks extending from your blister up your leg, this is serious and you need urgent medical attention. 

Okay, so you’ve decided you want to lance your blood blister. Perhaps the amount of blood accumulating is causing pain; perhaps the blister is too big and likely to tear anyway; perhaps you have to carry on running or hiking and need this blister deflated. These are all legitimate reasons to pop a blood blister… but only if you have the right gear!

One more time, remember, it is okay to not lance your blood blister. In other words, if in doubt, don’t pop it! Read this article to help you decide if to lance or leave alone, or watch the video below.

 

 

 

The Equipment You’ll Need

If you are going to lance your blister, here’s what you’ll need to do it so it doesn’t hurt and to avoid infection (below). This is a great little kit. We call it the Sterile Blister Lance Pack and we sell it from our online store. With expedited shipping, you could have one of these in your hands tomorrow so you can start looking after your blood blisters, infection-free. There are enough items in this pack to provide 4 blister lancing and treatment episodes.

 

Plus, I’ve included easy to follow instructions to help you every step of the way in lancing your blister safely and painlessly.  

On a related note, if you’ve got a black toenail, here’s how to treat it by drilling the nail. You can use the hypodermic needles in the Sterile Blister Lance Pack to perform this procedure.

Blood Blister On Your Toe (Or Hand Or Finger)

Whether you’ve got a blood blister on your toe or your finger, the principles of treatment are the same. It’s trickier on the feet though – not least of which is because we have to stand, walk and run on them. Our feet are subject to high weightbearing pressures and high contact pressures from footwear. As a result, these forces can undo any healing we are trying to facilitate with our treatment.

The other main difference between foot and finger blood blisters is our feet are generally a more germy environment, and so they’re more susceptible to infection. Think about it… our feet keep us in contact with the ground, which is a germy environment. Then we cover them in socks and shoes and keep them out of sight. Think about the warm, humid and dark environment they live in!

Please note that I am a podiatrist. In other words, I provide information about friction blisters on the feet (not on legs, hands, the face or elsewhere).

 

When Should You See a Doctor?

In most cases, you won’t have to see a doctor. As long as the blister roof stays intact, it is a sterile environment. All you need to do is remove the blister cause so it doesn’t get bigger or burst. However, if your blood blister pops and gets bigger or more sore or red, it may be infected (check these signs of infection). See your doctor for medical advice specific to your situation if things are getting worse rather than better.

If you choose to lance it, now you now know what gear you’ll need, how to perform the operation and how to look after it. Grab your Blister Lance Pack and do it safely and painlessly.

    I’ve been reading about but noticed most of these blisters arrive at the surface or just under. I’ve developed two…one on each each toe pad. They appear deeper and smaller about the size of a pea. Taking notice one was right where a sock stitching seemed to contact that area. Perfect circles put are uncomfortable. These are well below the surface. I don’t think I could drain easily if I wanted to.Thoughts….

  4. Rebecca Rushton 15 March 2014 at 2:27 am - Reply

    Hi Michael. Blood blisters and normal non-blood blisters both exist within the outer layer of skin. The thing with blood blisters is there is additional trauma to the dermis, the next layer down where the blood vessels are.

    When blisters look deep its usually because of overlying callus. Callus is thickened corneum, the very outermost layer of the epidermis. It can get very thick on weight-bearing areas particularly. I suspect this is the case with your toe pad blood blisters (but feel free to email me a photo – rebecca@blisterprevention.com.au).

    It’s usually best to leave them intact and remove the cause – that would be the sock in your case. But consider whether your toes curl over or claw when you walk. If so, a poditrist can help you minimise this so you don’t have an ongoing problem with them.

    I hope this helps Michael.Rebecca

    I have these blisters on my toes. I went to the Dr who did a Doppler test and he said it was from poor circulation. He said I should stop smoking and using caffeine. Can you elaborate on this?Pat

  8. Rebecca Rushton 17 February 2015 at 11:51 am - Reply

    Hi Pat. If you have reduced arterial supply to your feet (as your GP determined with the doppler), your skin potentially has a reduced ability to heal (cuts, scratches, blisters etc). The advice from your GP to stop smoking and using caffeine is aimed at improving your circulation. These two factors have a detrimental effect on your arteries.

    This article helps explain: Smoking and coffee combined have a greater harmful effect on arteries and blood flow:http://www.news-medical.net/news/2004/11/02/6034.aspx

    I had a blood blister on the bottom of my foot from my work boots … I tired to pop it many times but the skin was really thick which I found weird (normally I can pop them with ease) it made walking really painful after about two weeks it has gone down from a big bubble to a flat mushy black splotch on the bottom of my foot …. Never had this before its like really old black mushy blood …. I’m just guessing that it’s healing now and it will soon disappear?

  18. Rebecca Rushton 2 June 2015 at 11:59 am - Reply

    Blisters under calluses are trickier to deal with Chantelle. Interestingly, calluses and blisters are caused by the same forces – friction and pressure. Blisters occur when these forces reach a certain threshold that causes the blister injury (a tear under the skin surface). Calluses occur when these forces remain under that threshold. If this callus is new to you, consider how you might reduce pressure and friction (this might get you started: http://www.blister-prevention.com/blister-blog/blisters-under-the-ball-of-your-foot

    The black tissue is the bloodied blister fluid. As it gets older and more exposed, it will dry out (and go from red to black). As your skin layers shed, the blister pocket and its contents will move to the surface and peel away.

    I hope this helps Chantelle.

    Wow, I have had so many questions about big toe blisters lately!

    If this is a recurring thing for you Jacob, I suggest you see a Podiatrist. Because these blisters have a lot to do with how your feet work (where I talked about Windlass Mechanism). A change in foot function can fix these for good.

    While you’re waiting to get an appointment, you need to find a way to reduce friction levels and pressure. Good options were mentioned in the blog post (ENGO Patches for friction and donut pads for pressure).

    Great question Mary. It’s a bit hard to say without seeing it. But if the forces that cause the blister keep occurring, sometimes your skin can darken, kind of from the scarring. I doubt you still have a blood blister there.

    Feel free to send me an email with a couple of photos attached and I’ll be able to give a bit more considered advice (support@blisterprevention.com.au). But as always, it can’t beat actually consulting your doctor or podiatrist, particularly if you’re worried about it or if it’s painful – they can give you the most specific advice.

    The blood tends to go from a brighter red when the blood blister is new, to a darker almost black colour when the blood under the skin has dried. It sounds like it’s resolving, Morgan.

    I’m mainly just venting (because I’m in pain), but a year ago, I left an 8-hour-per-day desk job, in part because I was having complications from prolonged sitting: hemorrhoids! TMI, I know, but I was in some of the most agonizing pain of my life, (and that’s coming from someone who’s had a broken jaw and subsequent reconstructive surgery.)

    So, I now work at a job that has a lot more walking and standing, and I couldn’t be happier. I actually cancelled a surgery for my "sitting problem," if you know what I mean. But now, I’ve got these very painful blood blisters on my right foot. The first one started on my middle toe, which is the longest. And now, I’ve got one on my pinky toe. To make it worse, I’m clumsy, and I tend to bash this toe on things like furniture. Just tonight, I whacked it on my bed frame. When I looked, it was warm and throbbing!

    I wish I could de-pressurize the area, but unfortunately, all I can do is put a Band-Aid over it and wear my more comfortable shoes.

    I was riding a moped and didn’t realize the concrete on my drive way was the way it is. Well I had my feet down and my toe hit it hard! And now I have a blood blister I’ve never had one before! It isn’t a big one. I’m scared to pop it because I’m afraid of it bleeding a lot. Like I said it isn’t big it is tiny! What should I do?

    I seem to have developed blood blisters on both feet, on the next to small toe. They developed 4 days apart. The oldest one has now developed into a significant red rash on the top of my foot. I have also developed a rash over most of my body, in some areas, much more severe. I’m on prednisone from my doctor as well as some anti-fungal itch creme. The progression of the symptoms has slowed. Any thoughts on what the root cause is? My dermatologist is at a loss.

    I have two one on each toe from walking. It took about a week to heal and dry up but the scar is still there. This was about 3 weeks ago. Will Iever get my color back on my toe?

  52. Rebecca Rushton 22 June 2016 at 8:38 am - Reply

    The colour should return in time. Having said that, blisters that get deeper than the blister itself (an erosion) can scar and the skin shows a permanent lasting sign of that. But it will fade more and more over time.

    I have a blood blister on the side of my toe right where the bone is. Its been there for a week now. But what can I do for it if I still continue to run on it? I play soccer and I practice twice a day now and I can’t miss a day because our games are coming soon. After I practice the blister gets filled with blood and I can move it around. My skin is really soft and tender touching it. But it doesn’t hurt. I do where blister gel guard when playing then at home I put aloe Vera gel on it.

    Hi first of all thank you this article was very helpful, but I have a question. I was running on concrete barefoot and tripped and got a blood blister on my big toe. I had to wait 20 minutes before I could probably clean it because I wasn’t near my home. But since then I’ve cleaned it and done everything the article says to do in my situation. It’s now late at night and I can’t sleep because my toe hurts really bad and feels like it’s throbbing. Is that normal? Thank you!

    I have a tiny little blood blister on the bottom (pressure part) of my big toe. It’s just a little thing but hurts like crazy! It’s been there about a month. I’ve even taken to wearing little corn covers (those things with that little hole in the middle) to take the pressure off, but they’re really uncomfortable. The blister itself is kind of hard, but SO painful to touch. Any ideas?

    Hi, Rebecca. I found this article when I was throwing a goog on blood blisters. It was very informative. One issue I do have is your reply to a comment. When asked by Zetta ‘Do they Itch?’ you replied ‘Friction blisters don’t itch Zetta’. What you neglected to mention was that it does itch when you apply tape to it. As a doctor, you must be thorough

    Hi Rebecca,My husband came home with a large blood blister on top of his little toe. I mean covered the top all the way. It popped before he could get home from work. He soaked it Epson salt and applied Neosporin. He wears leather boots so we dress it with clean bandages. Weekend is here so we are airing it out as much as possible. BUT should we soak it more in epsom salt to speed the healing or not? I cant seem to find that answer anywhere. Thank you

  62. Rebecca Rushton 18 March 2017 at 10:55 am - Reply

    Angela, the aim is not to let the blister dry out nor make it too soggy by constantly soaking it. The aim is to keep a stable moist wound environment. Take a look at this for more about treating blisters https://blisterprevention.leadpages.co/blister-treatment-blueprint/. There’s a flowchart at the end of the download that will help and a link to a masterclass video that will help you choose the right blister dressing.

    I have a blood blister on the front of my pinkie toe after kicking a desk corner. It is about 5 mm in length and 3 mm in width, vertical down the front of said toe. I will be going to visit my partner in Melbourne in just under 7 days and we will likely be walking a lot at the national park and other endeavours. What advice would you recommend to successfully protect and look after my blood blister?
    Kind regards,Daniel

    Hi Rebecca,
    I’m on holidays in Fiji and was kicking a soccer ball around on very hot concrete. I started to feel pain and noticed 2 quite large blisters on each of my feet. 1 is the size of a 50 cent piece and the other is much larger. They seem as though they are only surface deep as they do not appear purple and dark in colour but I am unable to walk. I have applied ice so far and am sitting here wondering is there anything I can do to avoid spoiling my entire holiday? Is there anything else I can do? I can see the blood moving around under the skin and feel as though my best option would be lancing at this point. Suggestions?

    Hi, I went to a swimming area that has water falls and large climbing and hidden rocks in and around it, and i was swimming back to a rock ledge, and i though that it just drops off at the ledge, but there was a rock in front of it, and i accidentally kicked it, and now i have 3 poppy seed sized blood blisters on my big toe and they hurt. they are deep under the skin and I was wondering if they would still take a whole month to heal because of their small size

    October 16, 2017Hello,I have had a blood blister on my right foot, between my second and third toe. I am a diabetic who awoke from a one week coma in the hospital. Upon being released after 22 days, I went to see a podiatrist about this blood blister. He said not to worry about it. This happened in 2009.
    What are your comments, please.

  71. Rebecca Rushton 16 October 2017 at 8:35 am - Reply

    I have no comment B. I’ll default to your podiatrist’s advice as he has not only seen your blister, but knows about your medical history and what you’ve been through.

I seems to be liquidity still in the middle. I don’t remember hitting my toe anywhere. Do blood blisters heal in this manner or could it be something else? Any help will be greatly appreciated.

    Yesterday I danced a whole Zumba class barefoot on mattress, although I knew I shouldn’t, because it’s even forbidden to go barefoot on Zumba class and I did at home a couple of times and always had blisters after it, so I understood why it is forbidden – for some teachers and really not suggested from others – but yesterday somehow I forgot it and I was rather worried about my ancle that it might hurt. The reason I comment here is not only to tell everyone not to do Zumba barefoot, but I also have a question: how come that I had two small blisters under my both big toes, like on the first picture of this post, but luckily only their downer part, only under my toes or just a very little also over it, but one leg normal blister and the other is blood blister. Why? Maybe I made harder movements to one size? This is the first time I had blood blister too, I hope it’s enough for me to remember never ever do it again, Zumba barefoot. Thank you for your great article, it already helped me a lot to understand how it works and why did I get blisters at all, I just surprised how asymmetrical I am like this…

    One more question I didn’t see here the answer to: about all kinds of infections that I might have from blisters how could it happen? I mean only if my blisters open up and any infection enters to my body, or even infections might live already in me? Or is it possible that infections might enter through the skin of the blister as it’s less thicker?

      Complete blister healing time is 6 weeks. But read this: http://www.blister-prevention.com/blister-healing-time/

      I’m guessing your blood blister is intact. Therefore, the intact blister roof skin will keep all bacteria out so it won’t get infected. So you can shower as much as you like.

  85. Aiden 2 May 2021 at 12:06 pm - Reply

    So I do a lot soccer, and I developed blisters on the outside-bottom part of each of my big toes. My right foot became a blood blister like 6 months ago, and the left never got it. It eventually healed after about a month until about a week ago I got blood blisters on both of my feet on the same spots. I had a game today, and when I took my socks off, both blood blister had nearly doubled in size, but had never grown during any of my practices this last week. Should I be worried about that? Also, my left foot blister is on its early stages of discoloration, while my right foot is a very deep red, even though they appeared at the same time. Could that be a consequence of having had a blood blister on that spot before?

      Blister and blood blisters don’t usually occur with fissured heel callous Kathy. I suggest you see a podiatrist to see what that’s all about and get the best advice. Sorry I can’t help further. All the best :)

    I have a fairly large blood blister on the underside of my foot, about one inch directly down from the big toe. The blister is fairly large, between 1/4 – 1/2 inch round raise quite a bit; it is a dark blood color. I’ve had it a long time, about 30 years without it bothering me. It just recently started to hurt, but not too bad and only occasionally; doesn’t hurt when walking. One podiatrist looked at it and said I should just leave it alone; I wonder if that was a correct thing to say. Do you have a suggestion as to whether I should have it lanced? I do not wish to do that myself. Thank you.

    • Rebecca Rushton BSc(Pod) 15 September 2021 at 4:30 am - Reply

      I doubt it’s simply a blood blister Christine. You don’t have blisters that last 30 years. I’m afraid I can’t give you any advice – this would need visualising and assessment and an understanding of your past and current medical status. A podiatrist is absolutely the right person to consult about this.

    Hi. I play football (soccer) and tend to get a blood blister On the bottom of my big toe on my standing foot (left), right at the base before it gets smaller and attaches to your foot.

    What preventative steps can I take to help me not get more? Should my foot be snug in my shoe or not? Would vaseline help under a sock? Any particular socks help?

    I saw a podiatrist once that was staggered at the lack of mobility in my toes. I’m 28 and they don’t have much movement at all. They struggle to point more than maybe 45 degrees down and maybe 20/30 up.

    • Rebecca Rushton BSc(Pod) 16 September 2021 at 5:32 am - Reply

      Read this Jeff: http://www.blister-prevention.com/big-toe-blisters/

      So it sounds like you have a structural hallux limitus and you’re getting a blood blister under the interphalangeal joint of the big toe, with the blister fluid / blood tracking back towards the foot. In this case, an orthotic can only do so much, but it’s worth milking every last little bit of windlass mechanism facilitation you can get out of it. I’ll leave that part to your podiatrist to see if there’s anything additional he/she can get out of that. Then you’ll need to have the ENGO Blister Patch on top of the orthotic to reduce friction levels. The patch will be a more effective and longer-term solution to the vaseline, which requires reapplication as it moves away from the skin with your activity.

      Hope this helps.
