I am a 60 year old male. From time to time, during the night, I am awoken by a searing and increasing pain behind my lower lip and in front of my lower teeth. This takes about 10 seconds only but in that time, it feels as though my mouth is going to explode. The pain is in the 11 out of 10 range. I press the outside of my lips in the hope that this will ease the pain but it still gets worse. Suddenly it erupts into a large ulcer on the inside of my mouth. The one last night was about 1" long and 1/4" wide. Once it has exploded there is no pain but I can just feel a roughness where the ulcer or eruption is.
I have asked my doctor who has no idea and searched the internet with no luck. Does anyone have any idea as I really would like to know what is causing it.
Many thanks in the hope that someone might know
