Ive had severe diarrhea for 3 days now. When I say severe, I mean if I take one sip of water, one sip of water is ejected within minutes. If I eat anything (BRAT diet), within minutes it too comes right through undigested. The first day of this I went to the er. They paid little attention, gave me one bad of IV fluid and sent me home. Im also, dizzy, feverish, and my whole body hurts. I don't know if another trip to the er is a waste of my time and theirs or not. Help?
