Only cure to date I have found after suffering for 30 years with what I thought was itching, but have found to be pain. So 2000 I begged a Dr she prescribed 8 hydroxyzine.mg 25 . Since reduced to 4 with an extra one. I have since found per a Dr Aspercreme. It works! Also a prescription cream I can't remember the name. The white spots are scars from all the scabs from endless scratching and bleeding.
