I started out with a rash on my hands, next day I couldn t stand because of my right knee. The rash comes in more in the evening and seems better in the morning. I s on my knees,arms legs stomach almost every where except my face. I can walk but I m still having a pulling in my leg and lot of pain in knee. This has been going on for six weeks now. Still using cane, started out with a walker. My doctor thought it was a reaction to z pack that I was on. Now I just don t know, who should I be seeing? A rheumatologist or a dermatologist?
