Hi, I have had this itchy condition for about 5 days. I have a large red splotchy area and a red - not splotchy - area under my left underarm. I have two red areas - not splotchy - under my right underarm. My upper/inner thighs are red, not splotchy. None of these areas are raised or bumpy. Just very itchy. I have been treating the itch with Benadryl Gel - topical. It has helped, but the red splotches/spots are not going away. Except my thigh areas seem to have got smaller, but not gone away completely. What is this? Shuould I see a doctor? Thank you, in advance, for any help!!
