Skin surface symptoms and conditions

(33yr) Was given Omnicef for an ear infection. After 3rd dose broke out with huge patches of red whelps. Stop taking, but then my joints started to ache and I had large knots on the bottom of my feet and hands. Diarrhea and vomiting, severe stomache cramps and low blood pressure... followed by antiphylatic shock. While I was in the ER the discovered I was also having a heart attack.

It has been 3 weeks and every time I come off the steroids, the rash and other symtoms return.

Has anyone else had similar problems.
