View Full Version : One dark red bump in cheek of mouth

Jan 6, 2007, 10:48 AM
This mourning I woke up with a pretty big, dark red colored bump inside my mouth on my cheek. I looks like a blood blister but isn't, its so dark it looks black. It looks to be perfectly round. I looked at pictures of hpv and they are all white and nothing like the color of the one in my mouth. Any suggestions as to what it might be? I am a male and haven't had oral sex. Could I have got an std from kissing? The only other thing I could think it could be from is that I went to the dentist and got a cleaning and then got a filling in which they numbed the one side of my face but that was the opposite side then the side this bump is on.

I also woke up this morning with a similar blister bump that looks almost black. Did you ever figure out what it was?

Jan 21, 2007, 07:24 PM
No it just went away two days later and haven't seen it since

Have you found out what this is since I think I have exactely the same?

And now tonight it's gone. Had it for two days. I'm still bothered by its appearance and the fact that I can't find much information on what it may be. A blood blister, maybe? And if so caused by what? :confused:

Apr 19, 2007, 12:27 PM
Could it have been a cold sore?

Hi guys, I just got back from the club, and I also found a black blister inside my mouth. It's the first time this has happened to me. The dot is completely round, deep dark red, almost black in coloring, and about 3 to 5mm (0.11-0.19in) in diameter; it felt like a little bump inside my mouth. To be precise, inside my right cheek... now, I read a lot of comments just now, in webmd.com and some other blogs, and I found the one that says it's a blood blister to be the most possible option. I haven't had sex, or oral sex, or even kissed any girls in like... two... maybe month and a half, and I used protection, and all that (TMI?. just so you don't get scared like me, and think it's something worse... ), I have been stressed due to personal problems, and I also, could have bitten my cheek while sleeping since I've had a bit of insomnia for the past month, so I get lots of sleep during the day (probably drooling with my tongue out :D ), I also got a puppy recently, and I thought, hummm... maybe it's got something to do with the new dog... but to make the long story short, I just popped the blister :eek:!! It's O.K people, it didn't hurt at all. I rinsed it with water, and imagine that you have a small cut inside your mouth... that's the only "pain" but it's very small. Right after I popped it, a drop of blood came out, I tried squeezing some more, but only the drop was all I got. I'm not into feeling pain and all that crap, leave it to the bipolars :p, I just was really curious of what it was. Anyway, right now I'm about to rinse my mouth with Listerine, (mouthwash... I don't know how popular is that brand in other countries) and, give me 30 seconds, I'll be right back to tell you what happens... OK, I'm back, and nothing happened, just the usual tingling sensation. I'll post another comment tomorrow and in the following days to let you know what's happened. I hope this is helpful for other people who've just found that little bump inside their cheeks. And just for the record, I'm not a doctor, so, if you think you need to see one, do that... I also hope it's nothing to be worried about :confused:

It's probably a blood blister. If it changes in size or colour in the next week or 2 have it checked out by your dentist!

Feb 11, 2008, 05:39 AM
Sorry to intrude men, but I myself just woke up with this same red bump in my mouth. I haven't kissied anyone lately at all, I'm still a virgin and have nt had any intimacy of any kind. I kind of felt it forming but I just thought my skin was peeling. So if you guys figure out what it is, please let me know.

Hi I found exactly the same today inside my mouth on my right cheek, painless also, very dark red and near enough black. Looked up images of mouth ulcers and even mouth cancer! (as I smoke) but it doesn't seem to look like those thankfully... Only thing is I want to know what it is... I decided to Google the words "I have a dark coloured spot inside my mouth" and to my amazement I found it here... I feel a lot more relaxed now seeing that I'm not alone and there hasn't been many or any people write back to say it's still there or they've had it diagnosed.. Wait a minute.. that might not be such a good thing after all lol... Where are you all? Am I going to die in the next few days? Haha Just kidding... I will write back with progress updates :)

Try this chart.

I suggest you Google mucocele.

I have found a blood blister in the inside of my left cheek this morning. Its painless, but looks serious. I also found black spots on some parts of my body e.g legs and back. This was the first time I was experiencing something like this and was very concerned. I searched on internet and could not find much information. I consulted a physcian. Considering I had a viral fever 2days back, I was diagnosed with post viral fever I.T.P. (Idiopathic thrombocytopenic purpura). This occurs due to reduced count of platelets. I am asked to do a blood test for platelet count tomorrow. For more information on ITP, see Idiopathic thrombocytopenic purpura - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Idiopathic_thrombocytopenic_purpura)

Hey, I found this website because I too have a small dark red bump on the left side of my cheek this morning. Did all you guys found out in the morning too? Well, the thing is that I don't smoke, never had any form of sexual contact with anyone else before, and never kiss anyone else at all before... Has anyone found out what it is?? I will wait until two days before I pop this sh!t by hand...

Question: What medical condition causes blood blisters to occur in the mouth, on the tongue, and on the inside of the cheeks?
Answer: Countless conditions can cause blood blisters. To find out which one is the culprit, you need to pay attention to how severe the blisters are, and how often they come and go. You may also need a diagnosis from your doctor.

"If you find one or two that heal up within a week, it may be something as simple as stress, or biting or burning your cheek, and you probably don't need to worry," says Dr. G. Scott Heron, an assistant professor of dermatology at Stanford University. "But if it's recurring all the time -- and if you get multiple sores in your mouth -- you should seek treatment right away from a dermatologist or an oral biologist."

Recurrent blood blisters could signal problems that necessitate medical treatment. The most common of these is oral herpes, a viral infection that flares up periodically and has no known cure. Oral herpes signals its arrival with tingling or discomfort (a prodome) where a blister is about to appear. Soon afterward, blisters erupt on the tongue, the gums, or the cheeks.

Herpes sores commonly appear on the palate, starting as small blisters that soon run together to form one painful, large sore. Flare-ups can be triggered by stress, food allergies, dental treatment, mouth injury, or sunburn on the lips. Taking vitamin C during the prodome may help clear up ensuing sores faster. And taking herpes medication like acyclovir (sold under the brand name Zovirax) will inhibit the reproduction of the virus that causes the blood blisters in the first place.

If herpes isn't the trouble, you may be infected with some other virus. Or you may be having an adverse reaction to medication. You could even have one of the rare genetic disorders (like epidermolysis bullosa, pemphagus, and pemphagoid) that cause blood blisters in the mouth.

For a precise diagnosis, you'll need to see a doctor. In the meantime, if the blisters sting or itch, you may want to treat them with an over-the-counter mouth sore treatment like Orabase or Zilactin.

Ahh well I have the sammmeee thing lol, I'm sure its nothing unless it starts growing hairs xD I wouldn't worry about it ^_^ then again I guess I am 16 and don't really know much of anything, but ahhh, Chances are its just a blood filled Cold sore or something

Any sore in your mouth that doesn't disappear in 2 weeks should be checked by your dentist.

Oct 13, 2008, 11:57 AM
I have the same thing. It doesn't hurt and I just noticed it today while eating a cookie. I can't remember if I bit my cheek recently or not, but I have bitten my cheek many times in my life and never gotten a bump like this as a result. I am so scared.

Nov 8, 2008, 01:55 PM
Have the same thing. This is the only info I found on the net an so far nobody's reported back it killed them so I'm not worrying :)

Nov 8, 2008, 02:30 PM
Perhaps dowen, that is exactly WHY they haven't reported back! Lol

Just kidding, you'll live but as I've said, if it's not gone in 2 weeks it wouldn't hurt to get it checked.

Its called Leukoplakia. Its something you get if you have HIV or if you smoke frequently. If you have it you should go to your dentist or some oral doctor and have them remove it.

Nov 11, 2008, 06:53 PM
Leukoplakia is a white or grayish patch that is irregular or flat texture and can have thickened or hardened areas. These patches cannot be wiped away.
Leukoplakia is NOT a red bump.

Don't worry everyone, its called Hematoma aka a type of BRUISE. Some vessels were damaged, probably from accidentally chomping on your cheek like I commonly do, and blood rushed to and filled the area. If you don't remember biting your cheek you could have done it in your sleep, or eaten something really crunchy where you didn't realize it. Just leave it and be careful not to bite it again while it heals up. :)

I've had this happen to me twice within 2-3 years. The blister is definitely filled with blood. The first time I got this perfectly round blister inside my mouth on my cheek, I was scared sh!tless and started messing with it. All of a sudden it popped and disappeared as the collected blood inside it leaked out. It's been over 2 years since then and tonight I discovered another one. I didn't pop this one though. I don't remember biting my cheek... but yesterday I did feel some soreness on the same cheek the blood blister is now located... so maybe I did bite my cheek while eating or maybe in my sleep? I am also a long term MJ smoker, but I doubt it has anything to do with this blister.

I'm not going to mess with this blister as I want to see how long it takes for it to disappear on it's own. Hopefully it won't be there in the morning.

Hey guys,
I noticed that I too had a black bump on the inside of my left cheek. I smoke, so I was worried. I also noticed that this black bump was level with my molar, so I thought it was a blood blister. I tried to pop it, and it did. A small trickle of blood came out, and no apin followed. I suggest looking on where the black bump is on the cheek. If its tooth level where mine was, chances are you bit your cheek, which I happene to do often :). Hope this helps.

I too have had several of these blood blisters appear in my mouth in the last few months.  If you look closely, there will also be a small red speck adjacent to the blood blister.  These particular blisters are not caused by trama (i.e. biting, chewing, etc).  It appears that the blood vessel below the blister breaks from some other mechanism.  Again, there is no biting in the middle of the night regarding this condition.  There's no pain or discomfort in the onset.  It virtually appears in a matter of seconds.  It can be on either cheek or the tongue.  I showed mine to my primary care physician today and he stated he'd never seen anything like this before.  My guess is that he's in his late 40's early 50's.  Because it is so unusual looking, he did not want to break it for a biopsy.  Instead, he's hoping it stays in tact long enough for a specialist to see it in a few days.  What differenciates this blood blister from a trama blood blister is the accompanying small red dot adjacent to the blister. If the doctor's come up with something, I'll sure post it.
