[|Human|] I have a dry circular rash on my outer left thigh. Its 1.5 inches in diameter. Resembles a bullseye or ringworm. Does not itch. It had been there for 3-4 months. Three weeks ago patches of dry skin started appearing on the left  outer thigh and now on the rt outer thigh.  Now have about 10 patches each thigh. Sometimes get sharp stabbing or pin stick pain all over my legs or pain in my lower legs that feel like bad shin splints. Also  notice  a reddish purple rash covered by a silky smooth silvery white thin layer of skin on my left shoulder blade.  Two weeks later another one appeared on my right shoulder.

What is the cause of all the skin infections. Have noticed two spots on my face now. Hiv test  taken 3 weeks ago ands 6 months ago are negative.
