My doctor diagnosed it as 'dermatitis' but that is not helping my itching. Steroid cream helped a bit but I don't want to use it again and the itching is returning (or still there). The back of my neck, my groin, sometimes back of knees and occasionally left armpit. Why why why??? Does anyone have any idea re the cause? No known reactions to new products or foods, I don't know what to do next...
