I used to have problems with constipation but now for the last couple of months it's been sever cramping and diarrhea. I also have problems with indigestion (gross burps) so bad I vomit. The other night I woke up with a horrible stomach ache that got worse and worse. I went to the bathroom nauseated and was standing at the toilet when the pain became so bad that my legs started to give out and i thought I was going to faint then i sat down because I couldn't stand any more clutching my garbage can. All the sudden I had explosive diarrhea like water and threw up in my garbage can. The whole ordeal lasted two hours and when it was over I was so weak and tired and my stomach still hurt for two days.. :'( :'( :'(
I would definitely go to the doctor for that.
