I have had vasculitis of the blood vessels with rash since diagnosis June 17, 2017. My back hurts since June 10. Seeing a dermatologist, and rhuematologist not satisfied. Still have rash on all over both legs but no longer itch. Been on prednisone for 6 days,cephalexin, permethrin cream and now doxcycline hyclate. Nauseated and tired.
