agreed, with the posts above.. and as they said, shingles is only one one side of the body (follows dermatomes- you can search online to look up a dermatome chart)..

If you are on any immunosuppressants, that can sometimes activate shingles as well too

Otherwise, I get a similar rash from IVIG.. it blisters and itches/burns like crazy.. it is on my legs, arms, and when bad trunk, face and scalp too..
