I have extremely itchy, prickly feeling skin on my forehead with a rash, especially in my eyebrows. Not near any poison, no bug bites. This is the 2nd time in about a month I ve had it. It does go away, but drives me crazy. Last time I had welts on my belly and chest....none now though. I used cortisone ointment and it helped. But I d love to have a root cause..........any suggestions?? No new soaps, creams or makeup either!
