I have severe diarrhea and rotten egg smelling belching. Nos. Other than incontinence n pain from cramping. No one else at home is sick.?

Giardia vs difficile. Possibly an amebic infection such as giardia which often result in some cramping and foul smelling stool. If you recently used antibitoic, you may have c. Difficile colitis etc..Both conditions are treated with same med: flagyl. Sometime run-of-the-mill bug can cause your symptoms and usually resolve in few days. Peptobismol may help. If not better in few days, consult doc...Good luck.
