My wife thinks I am a hypochondriac and need help, but I can't help shake that I feel something is wrong.

Started off as difficulty swallowing. GP gave me Prevacid and referred me to GE. Had a endoscopy which showed small hiatal hernia and esophagitis. About the same time, I had a flareup of prostatitis, rectal itching, athletes foot and white coating on tongue (with burning at back of throat).

Went back to the GP who confirmed thrush. Started Nystatin.

I have perusing the internet, and have discovered a theory that all of my symptoms could be related to yeast overgrowth.

Can anyone help?
