For the past six months, I ve had a rash around several of my joints (not all at once--coming and going). The rash is extremely itchy. At first, a doctor thought it was fungal and treated it as such (it was around my right elbow and had a ridge at the edges; it also moved outward in a ring as the weeks progressed). It took 4-5 weeks to go away, all the while using an anti-fungal. It has now reappeared on the other elbow, one of my knees, and on my wrist. I ve been tested for Lyme because of the ring, but my bloodwork showed no Lyme titer. Could it be eczema? I ve had psoriasis, but it s nothing like that. I m using an ointment prescribed by my doctor, but it doesn t help much.
