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.

i just came back from a trip to the mountains. (it's loaded with tics) i always come away with at least 1. i got back last night and looked and saw nothing. then this morning i woke with a huge blood blister. is it possible that i carried a tick home with me and that it crawled onto my hand while i slept and caused the blood blister? if so what do i do about it. (i have never had a blood blister before, my platelet count is fine it was checked a couple weeks prior to the trip)

I get blood blisters from friction I think, but I've also had them in my female area. I know that its not an STD. I'm a virgin. But I now have one on my upper leg and on my stomach. I've just been told it can be caused by the friction of clothes or if your legs might slightly rub together the friction causes it. I've had my doctor drain one before and it was such a relief. If you have them and they hurt just go have your doctor drain them.

I am 22 and I've been noticing that just like others in several occasions I've had blood blisters appearing and going in my genital area. This always appears at the same place.... It comes and goes. I have to say it has left me extremely uncomfortable because i have no clue as to why it appears given that i haven't been sexually active for many years.

Can someone please enlighten me on the cause of this. I will schedual an appointment with my doctor because its really strange.

When taking a shower I notice on my stomach I had a

raised blood filled sac, it was very small but noticeable, I popped it and then it went away and then came back not as large, but it still came back. So now I am going to the doctor to find out what it really is, I am in a way worried about it, but I am going through menopause and weird things are happening to me anyways, so I will keep in touch and let you all know what I have

OMG!! I am going to the dermatologist in a few days, I have what looks like an irregular blood blister on my left breast and I have been looking online re skin cancer/breast cancer.......it comes and goes over the past few months. Stupidly, the first time I saw it I popped it and it went away for awhile. Anyone ever find out what these breast ones are? I don't get my period anymore but I take hormones....

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 armpit was itchy and i itches the spot and now theres a lump like thing but it popped tonight and it was only blood so im assuming it was a blood blister but its the second time its happened, the first time it was in my other armpit and when it popped it smelled like possibly my sweat gland was infected, can that happen??

i hit my foot really hard on a rock, and i got a blood blister. i have a track meet on saturday, and if i take 1-3 i go to states. whats the best way to heal it fast?

Ok, I just turned 14 two days ago and yesterday when I was taking a shower I found a blood blister down there...and I've had pimples there before. I'm kinda scared....Is something wrong with me?

i have one and i just popped it and the blood that came out was brown and it is march 28 and i have had it since february 22. it is weird.

Your son's boots probably rub his feet. He may need to find a different style or size of boots.

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?

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 have that same thing! I just saw it last night while doing my weekly "self breast check" in the shower... its weird... its not painful.. I just don;t know what it is...

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?
