Hi my gf noticed some strange spots on the upper right side of my back a couple months ago. It looks like I laid on something with a pattern and it left a imprint on my skin, but I have't. It goes away and comes back int he same spot. It never itches or hurts. The skin is not raised where the spots are. Some info on me, I'm 26, Hiv positive for over a year now. See the Dr. every 6 months and my counts are great and I am not on any meds YET. Any I ideas on what this could be?
