Blood blisters are a type of blister filled with blood rather than the clear fluid commonly associated with blisters. They are caused by a rupture of the blood vessels underneath the skin’s surface, usually cause by some form of trauma, such as pinching.

Like all forms of blisters, blood blisters form on the upper layer of the skin. They are the body’s natural response to pressure or injury. What differentiates them from other blisters is the fact that the trauma caused the blood vessels under the skin to rupture.

The most common area for these blisters to appear is on the feet, which are particularly prone to blistering. They are often caused by shoes that do not fit properly and pinch or put pressure on the feet. wearing properly sized shoes reduces the chance of developing any type of blisters as well as other foot problems.

A person may also develop blood blisters after being scalded or burned, including from sunburn. They can also develop in response to allergic irritants, viral skin infections, and fungal skin infections. Excessive friction, such as that caused by shoveling or raking for a period of time without wearing gloves, can also lead to their development.

For the most part, blood blisters do not require special medical attention. Those that are severe or that reappear, however, may require treatment. Similarly, those that are caused by conditions that threaten a person’s health in other ways, such as burns and infections, should be checked by a medical professional.

When caring for blood blisters at home, people should try to avoid popping them. This can lead to infection and can slow down the body’s natural healing process. Blisters should be covered with a soft dressing so that they are not disturbed as they heal. If the blister does pop, the resulting pocket of skin should not be peeled away. Instead, the body should be allowed to heal the area on its own schedule.

Blood blisters should also be washed frequently in order to keep them clear of irritants. Applying zinc cream to the area can also help dry up the blister and speed the healing process. When the blisters break, however, they should be treated with antiseptic in order to prevent infection.

I recently lost my wallet and had to get a new one. After about a week, maybe two, I got a blood blister right where the new wallet was rubbing. Thankfully on the outer, fleshy part of my butt, rather than the crack. I am just a tad confused on how to treat it. Do I shower daily and let it bleed as it wants, or do I avoid taking a shower until its gone?

So yesterday, I was packing a box in my family room, and all of a sudden, I felt a rush of warmth to my lower lip, and then could actually feel my lip growing. I looked in the mirror and saw a blood blister about the size a large pea. I iced it. There was nothing near my face when it appeared and the bump has reduced. However, it remains numb. Any ideas? No insects, bees, spiders, etc were anywhere near my face.

I have a recurrent blood blister on the right part of my upper butt. It is always in the same place. I get it maybe once a year. It is not painful and there was no damage or friction in the area. I have looked on websites for help but they all say pressure or something like pinching causes them. I have neither where it's located. I am just wondering if anyone knows why I would get a recurring one always in the same spot and if I should be concerned.

@anon234279: You need to see a doctor. Period. I doubt it's an STD, but if it is, it can probably be treated. And if it is an STD, your girlfriend may need to be treated as well. Do you want *her* to have an STD because *you* won't see a doctor?

If you care about your girlfriend, you need to get this checked out so both of you can have some peace of mind, and also, if it happens to be something serious besides an STD (which I also doubt), then the earlier you catch it, the easier it will be to treat. You can have conditions involving the sex organs that are *not* STDs, you know. So you need to find out what this is.

I was recently doing a self examination of my genitals and noticed that I have a small reddish blood blister on the bottom of my scrotum. My girlfriend says it was there the last time we had intercourse, but she was embarrassed to say anything should it hurt my feelings and didn't think much of it at the time.

Anyway, it doesn't hurt, but my girlfriend did try to pop it with a sterilized needle. It bled a little bit, and seemed to recede, but then recently it reappeared after about a week or so. Now my girlfriend is afraid to have sex with me, because she thinks it might be an STD.

I am so distraught now, because I really love her, but I'm afraid she will leave me now for another man. It's been three days now and she still won't have sex with me. Will this go away on its own or should I go see a doctor to look at it? I kind of want to see the doctor about it just to prove it's not an STD, but then again, what if it is? Do you see my dilemma? I'm damned if I do, or damned if I don't.

I just want my life to be normal again - especially my sex life, which has been non-existent now for three whole days. However, I guess it won't kill me to wait a few more days.

To post 70: If it is on the labia, then it is a Bartholins gland cyst and your doctors should know this. Dirt gets in the gland opening and then the gland can't drain. This is a painful area for a cyst that yes looks like a huge blood blister and it will swell until it pops open. The normal treatment is antibiotics to get the swelling down and for it to go away on its own. If it is truly bad the doctor will lance it. This is from my own experience with the cyst.

I suffered head trauma during a car crash (into a tree) and all my scans are ok, but I had a huge knot on my head just over my temple filled with blood for three weeks. Today, it popped and a bunch of blood came out, leaving a smaller knot, but a dull ache over my eye. Should I just clean it, or do I need to go see a doctor?

What a lot of people are posting about sounds like angiomas, which are harmless clusters of blood vessels forming at the surface of the skin, usually in the form of a small red bump. They are usually rather small, but can become the size of a pea or larger if broken open multiple times.

They are more common with age, and a dermatologist will generally not even bother removing it unless it has become large or infected. Removal of a typical angioma is considered to be for purely aesthetic purposes.

Blood blisters are different in that they are formed from a minor trauma to the skin which causes a blood vessel to rupture under the skin, usually from a pinch of some sort. If you are concerned about a spot or group of spots, see your general doctor, and if necessary a dermatologist.

I don't know if this is a blood blister, but I play sports and I'm guessing this is caused by a bunch of pressure/rubbing from my cleats. Today I noticed that the once white blister on the back of my big toe had a more dark brownish color, and then later today it popped and brown fluid came out-yuck! I don't know what this is but I'm not really sure if this is serious or not.

Come on people. We are talking about blood blisters here. Maybe 2 percent of you might have cause for concern. Does this site have an age limitation with respects to posting a question? It sounds like most of you should be asking your moms these questions. I know this comes off as possibly mean or rude and I don't mean to offend anyone, but God help you should you ever get something really serious. Let's get some perspective here.

You might want to consider going to one of the medical sites on the internet and perhaps, do a little reading. It's amazing how much information the internet can provide. It just takes a small amount of time and effort.

If at that time, you cannot find an answer, then come and ask your questions. I apologize if I have offended anybody, but I have to say, I was offended by just reading most of the questions.

I have this 'thing' on my bottom lip that always was there after I suffered an accident many years ago. That area was cut almost nearly all the way through, and had to be stitched with 20 or more stitches.

Many years later (about 25) I get this 'bluish' small spot on my lower lip. Hmm. Not noticeable unless I became cold or stressed; then it would appear. It is now bigger and noticeable almost all the time. And recently (three days ago) it has a small bump on it, that was not ever there before.

It is perplexing to me and I do not have insurance to see a doctor It is not very attractive, but that is my least concern. It seems to have changed rapidly in the last few months, and now I have this bump on it (or inside of it, as the case may be).

Is there a correlation between this accident years ago, and this spot that has gotten bigger with time and is now noticeable more than ever? --SL

Oh, I feel so bad for all these people. They're so scared.

There are two kinds of blisters: 1) blisters caused by physical tearing between the upper layers and lower layers of the the epidermis, and 2) blisters caused by damaged or abnormal lower layers of the epidermis where skin cells are born (basal layer). The first kind is nothing to worry about. The second kind can be problematic.

If you have good reason to believe it is of the first kind (almost always the case on palms or bottoms of feet) then don't worry. If blisters keep returning, then the basal layer was probably damaged and may take a long time to heal without intervention and you might need to see a dermatologist.

If it is of the second kind and larger than a BB and sensitive, then you should see a doctor. If it is smaller than a BB, or not sensitive, then it is probably not dangerous, so don't panic. Give it time to go away.

In most cases you should not pop a blister as its existence is part of the healing process. However, there are exceptions:

If it's filled with pus and somewhere where clothes rub (waistline) or skin takes a beating (elbows, knees) it's possibly staph, or perhaps even MRSA, so get help immediately. It should be drained and if staph or MRSA, you may need special antibiotics, but if viral then no antibiotics.

It could also be a spider bite and the proteins injected by the spider have damaged the skin so fluid is injected along with blood to suspend the proteins while keratin is injected just above the basal layer to project the basal layer from damage. In this case, it should be drained, preferably by a doctor.

If it's painful, say from an ingrown toenail, it may need to be drained. Painful blisters that feel like they're going to pop inwardly should be drained. These, however, should be done by a doctor. If no doctor is available, make sure whatever instrument you use is above all, germ-free. Remember germs are invisible - a match will kill them though. Don't wash it off as tap water has bacteria.

Second, thoroughly soak the drained area with hydrogen-peroxide (3 percent H2O2). I recommend making a drippy hydrogen-peroxide bandage and leave it on overnight. Hydrogen-peroxide (3 percent - don't use 30 percent!) is the safest and most beneficial antibacterial for your skin. It will oxidize any foreign organic protein (poisons, bacteria, viral infections) causing the blister and is harmless to living human tissue.

If it keeps coming back in the same place, even if only twice, see a doctor. Although it's probably only damage within the epidermis, it could still be an indication of skin cancer though you should only anticipate it if the location is where you've received the majority of sun damage (shoulders, nose, etc). Be aware of this if you had lots of sunburns as a youth.

Sometimes blisters will form due to stress and bundles of blood-vessels just over-reacting. Sometimes vaginal blisters and around folds of skin and fatty issues are related to that. Get some Vitamin B.

If you get frequent, inexplicable blisters, also make sure you get enough Vitamin C and E to generate the collagen and keratin your skin needs to keep those epidermic layers glued together. Fish oil and lecithin granules might also be helpful to put your body's oils back into balance.

You might also want to consider a microneedle roller (order online) along with a paste of pure ascorbic acid and your favorite lotion (also order online) twice/week which you can do at home. This will build up the collagen in your skin.

A lot of these comments are just ridiculous. You don't get blood blisters from 'bumps', and they generally don't keep recurring for no reason unless you have some kind of genetic disposition of weak arterial walls (one such symptom is hemorrhoids but its not the only cause of it).

Bruising is different from a blood blister, as is a 'cut lip' that swells up from inflammation, followed by fibrous tissue, which is the normal process of tissue repair.

Also if its a 'pin prick' size, it's clearly not a blister. In fact, it would make more sense to make the misdiagnosis of varicella or some kind of fungal infection or rash.

As the article stated, blisters are generally caused by rubbing (constant), and blood blisters when there is pressure involved causing the blood vessel rupture.

If you have something else, you are better off going to your General Practitioner who is your primary point of contact for health care. There is no reason to go to the ER unless there are other symptoms presenting as well.

Petechia or Pupura* (pin prick hemorrhages that can be caused by scratching and are usually flat to the skin)

“blood blister”* (caused by burns, friction, pressure)

skin tags* (idiopathic[unexplained] and mole-like, grandma probably has a lot on her neck)

shingles (Painful blistery rash patch usually occur in bands on one side of the body) notice progression of the rash and pictures, may cause residual nerve pain.

Hives or urticaria* (caused by allergic reaction or stress) Flat, wide, and pink.

Genital herpes (viral std predominant in the genital region, nose, lips, mouth, throat)

primary syphilis (more ulcer like)

friction blister* (can be caused by things like tight clothes, uncomfortable shoes. Raised thin layer of skin filled with clear fluid and/or blood, relatively painless unless ruptured.)

I've gone through and read some of the posts on this page and these are a few things I think you guys you google and google image search. Although the internet is a dangerous tool for hypochondriacs it's also might save you a trip to the doctor. The majority of the things I've seen described seem like simple friction blister that I'm sure have cleared up by now unless of course the friction and pressure haven't been relieved.

*Should pass without medical attention unless accompanied by another worrisome symptom such as anaphylaxis or severe pain.

For those of you who are finding that you have small pin prick sized blood blisters randomly over your body, and doctors dont have an answer for it... ask them to do a platelet count.

Last year, i thought i had a rash on my legs because i had little red spots all over both.. from my ankles to my thighs. i didnt think too much of it, until i started getting blood blisters in my mouth for no reason. then they started appearing in my throat, and on my tongue.. which is when the red flag went up.

i went to the ER (it was 2am) after i noticed more red spots all over my feet... and i was diagnosed with ITP (Idiopathic thrombocytopenic purpura). My platelet count was below 10,000... where normal levels are between 150,000 and 450,000.

i was kept in hospital for 2 weeks and underwent immunoglobulin infusions, and was put on steroids to bring my count back up.

my ITP was misdiagnosed 3 years prior, when i had these same symptoms occur, along with multiple unexplained bruising all over my body.

When i went into the hospital, my platelets were so dangerously low that i was at risk of bleeding out internally had i had some sort of trauma occur.

my son is getting blood blisters on the bottom of his feet. All he wears are his boots. Does not go bare footed in the house or outside. Normally when he wakes up in the a.m. they are there.

I don't understand this. You guys are talking about how you just woke up with them. The other night I hit my toe very hard against a drawer. In the first few seconds it was purple, so I figured it was a bruise. Within a few more seconds it became round and a dark red. That was when I realized it was probably a blood blister. It isn't a bright red like it has been described. Its a dark red, almost brown. Is it definitely a blood blister?

Um... I have the tiny red "blood spots" all over my arms (that i have noticed so far). They are about the size of a pin head. What are they? and Why are they there?

Moderator's reply: Of course, you should always consult your doctor if you have health concerns. check out our article, What are Campbell de Morgan Spots? - it may have more information on your red spots!

Antibiotics are used to treat bacterial infections. They can't cure viral infections. I'm not sure why your doctor gave you antibiotics unless it's actually bacterial. I hope it works for you.

I am the second anonymous.

I finally decided to see the doctor about the blood blisters -- after one showed up in a worrisome area. She said that they have nothing to do with cleanliness, but didn't know what to do but treat them as they appear. She said they are caused by a viral infection in the skin and gave me antibiotics to treat this particular episode.

Obviously I don't have any new answers but I want to recommend everyone see a doctor if they haven't because it would have been nice if I hadn't had to wait until my monthly was over with to get the antibiotics -- she had to inspect the blisters.

I am only 17 years old and this morning I awakened to find about 5 or 6 little 'blood pockets' or so I've been calling them. Each of them had a tiny 'ball of blood' in the middle which falls off. now they are flat to my skin and I haven't a clue why a 17 year old get's something of this sort. my dad claimed they were so called 'tags' yet no cells or tissue remain attached to these flat surfaces... could it be blood blisters?

I was born in September 1933 and had little blood blister on cheek. I scratched it and it bled profusely. The doctor told my mom to tie my hands to the sides of the crib to keep from scratching. It healed up. But later on more appeared on my body, from under arms to upper thighs. They do not itch though. They are blood red (really) and about the size of a pin head to twice that size.

They do not go away either. I thought they might be classified as petechiae, but not from the definition.

I was scratching my arm because it was itching, and blood blisters formed. I also have tiny blood spots in numerous places, including my breasts. they are, for the most part, very tiny. The few on my breasts are larger, and I have no idea how they got there.

I am at a loss as to what the reason is.

Can anyone tell me?

I also have been getting blood blisters monthly - usually right before my monthly. I was beginning to think it was my deodorant becuase they were under my arms but this month it appeared on my upper leg. I would love to know why they come and how they are connected to my monthly. I was going to go to the doctor but if yours can't figure it out why waste my money?

Unfortunately, I experience the same thing; usually there are only one or two, always on the breasts, and for the past four years neither doctors nor dermatologists have been able to find out what they are or why they're there.

I am working on my own to figure out what triggers them and am starting by eliminating caffeine. I am also trying castor oil packs to see if they alleviate the pain and discomfort.

I'll let you know if I have any success. Good luck!

I continually get what looks like a blood blister. I got it the first time 3 months ago. It eventually went away (after 2 weeks). It came back last month and again went away after about 2 weeks. Last night I went to bed and woke up with another one this morning. I have had this a total of three times now and it seems to come once a month just after my menstral flow. It has formed in the same location each time (on my right breast). Is there any corelation?
