I went to the doctor yesterday because I thought I had food poisoning which persisted for 24 hrs. Vomitting, diarrhea and severe cramping. I was given phenaphin 25 mg. to help with the nausea, but the pain in my left side persists. I notice if I try to expell gas, I get mucous and in the morning there is blood and clots. Is this indicative of something else. I'm trying to do the cultures, but I haven't been able to "go" yet to get the stool. I'm terrified about the blood and mucous and pain in my side.
