For the last 2-3 weeks I have at different times of the day just start itching all over. My arms, my legs, my back, even my scalp. I don t know what could be causing this to happen. I relieve it by taking OTC Benedryl, but I have to take like 4-5 tabs at a time for it to work and I know this is to much. My question is, is there something else that I can take to relieve this problem. Or do I need to go see some type of specialist.
