I noticed if I go more than 12 hours or so without using my pv I start to itch really bad. My feet my arms and hands and my back. I have open wounds from scratching them so hard. It's pretty gross. I have tried anti itch cream but nothing seems to work. And the problem doesnt end there I get itchy even when I do use my pv. I'm going to take some benadryl and see if that helps. Does anyone know what could be causing this?
