Hi. I have been getting a evening/nightly rash on the palms of my hands and the arches of my feet for about 3 months. The rash is red and very itchy. The bumps do not come to the surface of my skin, or at the least, they are very flat. The rash disappears by morning, but usually reoccurs around 7 or 8 pm. I have not changed any products such as soaps or detergents. It occurs whether I wear shoes/socks or not. As the rash occurs before I go to bed at night and regardless of my location, I know it is not my bedding that causes it. I have taken Benadryl and used anti-itch lotions, but they provide no results. Can someone please tell me what's causing this or what to do to relieve the rash?
