Hi, I'm 67 And Have Had A Shingles Shot About

Hi, I'm 67 and have had a shingles shot about a year ago. About two weeks ago I got a patch on my back that I know was shingles, my doctor said you can get a mild case even after the shot and because it was past 48 hrs she said there was nothing that needed to be done. So, last night we went out to eat and I bad shrimp and catfish. This morning I got up and have spots the size of a pea and there red and itchy. I have one on each shoulder blade and the rest are on my stomach and one on my chest. Question is, Is it shingles or hives? Kathy Ziemba
