I had never had one of these until about three weeks ago. I am on a meal-replacement diet and notice that it happens right after eating one of the bars. It will go away and then recur within two or three days. It looks like a pimple, but I cannot pop it. I have a doctor's appointment tomorrow for an unrelated matter, and if it is still there, I will get her to look at it and report back.
Geez! I have one of those things on the inside of my lower lip. Doesn't hurt. But it feels like I have a Tumor! So annoying! I just want to poke the heck out if it! Makes me look like I have a fat lip!
Just a follow up. Went to a specialist soon after my post Jan 30th 2008, they cut it out and did a biopsy came back as showing nothing sinister, in fact nothing at all. The blister went away then came back but to a much lesser extent for about 2 months on and off and then it disappeared completely and it's not bothered me now in almost 3 years... What a relief! I actually put this down to a mouth injury caused by a very sharp piece of pork crackling breaking off and cutting the roof of my mouth. Every time I ate pork, it was like my mouth was allergic to it. It must have taken a while for the pork to break down and disappear from that region. So if you have this, maybe you accidentally cut your mouth or caused an injury to one of your small saliva glands up there. It will go away eventually, but get it checked out anyway like I did.
I too am so relieved to read this, I've had this off and on for many months now, the exact same symptoms, SAME spot all the time! What I'm finding is working is to take Reactine, this stops the post nasal drip and I don't usually get the blister afterwards. I feel better at least knowing its not something more serious although it is very annoying at times!
aw what a relief. . .i have had this experience as well . . .have searched Internet to no avail (in fact Med Help has another section where this question was asked and doc couldnt answer!) And my clear blisters dont last long enough to diagnose. . .mine also form within hours. so all same symptoms.
I have found that if i do get a blister i am careful to pop it into a paper napkin so as to absorb the liquid. I have found that this drastically diminishes reoccurrence. My theory thus has been that it could be a purging or detox of some sort as just simply popping a blister in the past has created more.
Incredible, I have the same exact thing and was concerned it might be herpes!
