I have been itching all over for 4 days. can not sleep, have not changed laundry detergent, or shower gel. I do nit use hot water, only warm. I've changed sheets, washed mattress cover. I have been taking Benedryl, 2 at a time but to not much relief. Ofcourse, I've been wetting myself down with moisture creams. I am going thru a LOT of stress right now. could that be it?
