I am 50 year old male with thyroid levels asunder as on 2 april 2015:- t3 - 1.90 mg/ml t4 - 11.87 mg/dl tsh - 0.010 mu/ml I have been advised neomercazole (carbazimine) 5 mg. But for the last 3 months I also have severe itchy patches (thickened and scaly dark skin) in the groin area of the thigh but not on genitals, which causes a lot of itch and scratching. Smaller patches have also appeared on my neck and chin, red and itchy. Please diagnose and advise.
