Hi, Last friday night I started to get very sick, by saturday I had severe diarhea and weakness so I went to the emergency room. They told me I may have had a food bourne illness so they gave me an iv for fluids and sent me home. I started to feel alot better. However, during my illness I did not eat for 3-4 days. Once i started eating again I had terrible stomache cramps and could not have a bowel movement. When I do, it s just liquid, I can t have a solid bowel movement, and my stomache is bloated and i feel nauseous.
