Hello, Recently I made a trip to Las Vegas for 3 days. One of the days I went to a renown restaurant and ordered a steak, medium rare. Well when I bit into the steak it was much more red then I remember medium rare should be, but I finished the plate. The next morning was the trip back home, and I had a real bad stomach ache, and felt the need to vomit, but didn t vomit because I dislike doing so. I get home, nothing but Diarrhea for the next 7 days, I figured food poisoning. However, up until the 7th day of Diarrhea I started getting hives on my body. Nothing of my home routine has changed, and this is a first for any kind of hives for me. Is there a correlation of Diarrhea for 7 days and hives?
