I have had a rash on my elbows and the top of my feet on and off for several years. I never sought treatment for it because it came and went and really wasn't that difficult to live with. However, four months ago, it spread to my upper arms, upper back, thighs, and around my knees and now it is very difficult to live with. It looks like small pimples, is very itchy, and leaves scars. My GP put me on antibiotics for it. The first antibiotic (I don't recall the name of it) for 2 weeks and now doxycycline. I have taken the doxycycline for 7 weeks now. The antibiotics have not helped and I am not convinced that it is bacterial. Any suggestions you could offer would be very much appreciated.
