Hi, for the past few years I have had a constant dull pain in my stomach with an occasional severe pain that radiates down the right underside of my rib cage. I've been to the doctors numerous times with them telling me it's "anxiety." Its definitely not because it is so severe I cannot move at times. It is not a UTI, I am not pregnant, not STDs, and not an ulcer. They don't seem to believe me and I cannot narrow down any food in particular that causes it. Also, I constantly have dry mouth and my hair has become thin and falls out. I am only 23, BMI 22.
