I am having an odd issue. over past few days I periodically will feel welts develop in my mouth in both cheek areas. It will subside after a short time. Tonight it also occurred inside lip. It has almost subsided. There s no pain or lesions. I have.t changed diet. I am exercising more but that s only change. I otherwise feel fine and had physical last week and blood work normal.
Small trauma keep occurring in side The mouth and when they heal it forms welts. If you have a habit of lie and check biting then you may have welts more.
