I had a osteroscan on oct.22 and now i have a severe rectal rash, and skin rash on hips legs and arms itching. The rectal rash seems to be spreading, and has had clear liquid pouring out if. I have had diareha for years, (10)but the rash started after the ostero scan. They said I have a pheochromo on my right lower lung, but gave me the ostero scan to look for carsanoid, which was negative.
