I have almost constant diahrea...Abdominal pain/discomfort, all over body aches and pain, mouth sores and hot flashes.?

See a doctor. I hope this has not been going on very long, because it sounds miserable. If it has just been a day, then rest, drink plenty of fluids, eat the brat diet (bananas, rice, applesauce, toast), and it should pass. If this has been going on for more than a couple days or is getting worse, you need to get to a doctor as soon as possible.
