I have skin rash, that is spreding in all of my crevice areas. it is in my scalp, ears, eye lids, arm pits, groin area and legs and 1 patch on my right fore arm. the sores begin as a red sore tender spot and then in a couple of days form a white pus filled head. I had a blood wellness and STD work up and all results were negative except for High Lymphs . I cannot see a dermatologist until Thursday the 9th. Could you give me an idea of what might the cause be?
