From what you say, you're symptoms
don't match shingles
(herpes zoster) at all. Singles would be a sharply localiized patch, only on one side of the body, and typically very painful. See your doctor as planned, but I'm sure that's not it. And even if it is, shingles defintely does not mean you have HIV. It's only slightly more common in HIV infected persons, and even then it's an issue of people with longstanding infection, typically for several years (i.e. with advanced immune deficiency).
