A weird mouth symptom. had my jaw yesterday, both upper and lower jaw just on one side, feeling like I had jaw inflammation along with a touch of sore throat, which made me wonder what kind of infection was going on (ive had that jaw inflammation feeling symptom before), so I looked inside my mouth to see if I had another herpes outbreak or anything weird showing which could be affecting my immune system and jaw. Anyway there was something interesting there to see, I had a red/black spot in my mouth. (I tried to get a good photo of it but it hasnt turned out clear, it looked more black then it's red appearance the photo, Ive had similar dark spots appear (but with herpes looking like bumps before) ..but the black spots when I get one of those completely black /brown ones, some have looked like mastocytosis freckle. This time I had no herpes like bumps as such in my mouth, just this one strange spot, like a black/red strange "blood vessel spot" thingy (it had like small blood vessel lines going to the dark patch).. it wasnt sore on the very spot thou, the soreness felt like deep in that same side jaw. My boyfriend thought I must of bit my mouth or something in that place..but its behind where my teeth are and that place my teeth cant even reach. The spot then did as I expected what happen, went away when the whole side of my jaw stopped feeling inflammed (note the side of the jaw affected was the same side as what the spot was on too) . Im sure these strange mouth outbreak things are going with other symptoms Ive found before I get with them. (not clear in the photo as I said but see that little spot I have the torch light on). Its only a little thing but its happening for some reason!! Anyone know what may be going on here? What causes mouth spots, deep inflammation feel (that side of my mouth inside was also redder then the other side) and can also give a sore throat? Is this a vascular spot outbreak thingy?? or some kind of infection?? mastocytosis?? different presentation of herpes?? (I'd love to get one of the spots analysed at some time, but when I get this symptom complex, they usually last average only 12 hrs (up to 24hrs) so Ive never been able to show a doctor these spots. This one came up in a new place to what Ive previously had them in my mouth (they usually are on the roof of my mouth when one appears, this is the first behind my teeth at back of mouth). This can also happen to me as a postexertional symptom too or when more run down.
