Have you seen an oral pathologist yet? They deal with diseases of the mouth and would probably be more helpful than a family doctor. Also, have you been tested for H. pylori? I’ve been experiencing problems in my mouth, throat and stomach too. I think some of it may be due to the anticholinergic effects of the psych drugs. They dry you out, for one thing. I hate the way I feel on them and wish I could go off eventually, but so far have failed in my attempts.
