Monday night I developed bad abdominal cramping and diarrhea..The diarrhea continued a few times that night then it stopped. THe cramping has continued even though I have normal bowel movements now. Sometimes the crapming is in the lower abdomen and some times higher up above my belly button. It isn't constant, but sometimes lasts for hours at a time. Heating pad helps it some. I thought it was food poisoning but it hasn't gotten better since Monday and I am not nauseous or having diarrhea. I went to doc who did CBC and it is normal. She put me on Bactrim, I just started it yesterday, but so far no improvement. What else can cause this cramping? It is bowel related since I did have that bad diarrhea the first night...Any ideas are appreciated..
