Talk to Dermatologist on Skin Issue

I have been receiving eczema treatment from 12 years. Last month I went to NIH and doen my skin prick test. it showed protein allergy instead of eczema. I have stopped all form of protein but still my symptoms are mot improving. Also my oozing eczema have stopped responding to steroid creams an ointments. Plzz suggest what to do. It has spread all over my body and is increasing day by day No cream and ointment is working I am also taking anti allergen but all in vain .
