6 Months Ago I Started A Skin Itching On My

6 months ago I started a skin itching on my earlobes and my PCP gave me a script (pill) that contained sulfa. I found out that I was allergic to sulfa. My journey started with the skin itching. It went to my arms, lower leg and blisters on bottom of my feet. I went to two different my Dermatologist, one recommended Triamcinolone Acetonide, Fluticasone 0.05% another time, Mupirocin Calcium cream 2%, another time, and Hydrocortisone ointment 2.50 strong steroid. I am a cancer survivor and very careful about steroid and most medicines. During that time I had two courses of Prednisone and two courses of antibiotics. and He just prescribed for me Atrapro Hydrogel. had a biopsy done in November. results came back dermatitis psoriasis. non of these steroids have worked to totally irradiate these symptoms. I can't find much information about the Atrapro Hydrogel which I only used it once so far. Tonight will be my second application. I'm sure this sounds so confusing but can you make any sense out of my issue?
