Hi have chroins and had an infusion Thursday it s called Entyvio, all went fine no reaction but by Friday night I was experiencing stabing pains in my atomic? I did vomit and about 3:00 am had a bowel movement and the pain stopped. Thought it may be a stomic bug but no fever, did have the sweats last night. Still not feeling well stomic grumbling a lot and passing gas? Have only eaten crackers and liquids today? Could I have food poisoning for I ate lunch at a resurant on Thursday and Ice coffee on Friday that wasn t from my home?
