Inside of my mouth keeps peeling a few times a day, numb and tingly feeling also. It also goes through a stage where my mouth feels like it's being scalded. This has been going on for months and no one can tell me what is wrong with me. Also a few months ago I was eating a salad and the left side of my mouth started to droop. I went to the hospital thinking i was having a stroke, but the doctors have ruled out a stroke, all my tests, blood work, cat scan, etc.. all show everything is normal
