I started a rash on my face and back and shoulders. It doesn t itch, but has started flaking my skin from the tiny bumps. My hands and end of my fingers are very dry and cracking,and my nail beds seem to be shrinking and getting smaller. I went to the dermatologist and she prescribed some cream to rub on twice a day, but it doesn t seem to be clearing it up, and it s been almost two weeks since I started the cream. My feet callouses are getting very tough,also, making it painful to walk on them.
