I have lupus and am currently in a flare (red cheeks, etc.). I fell 3 weeks ago tomorrow, so I know I've compromised my immune system with that as well. I've a quarter-sized area on my right buttock near the base of the spine. It's itchy, painful and uncomfortable. Could this be shingles? I've never had it, although I've run the gamut of rashes with the lupus. This is new. I see my rheumatologist tomorrow...is this something he can help with, or should I call a dermatologist? I was treated months ago with Neurontin for facial/cranial nerve pain...same side.
