yesterday the bottoms of my feet began itching like crazy. i have no peeling skin and no odor. haven't changed anything in my daily routine......no new socks, no showering in a weird place, not around anyone new. no new shoes. i also seem to be having weird small patches of hives/itchy welts in random places over my body the past week or 2. the one morning i woke up with hives all over my forearms. i dont understand what they could be coming from. I have been doing everything exactly the same the past few weeks and haven't eaten any new foods, brought anything new into my house or anything. what could this be? thanks!
