One dark red bump in cheek of mouth
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.
