for about 4 months now, ive had this rash on and between my knuckles, which first started off as red and later weeks deepened to purple, kind of ashy, i went to doctor 3 times and was told it was only ringworm
, i was prescribed nystatin and triamcinolone
acetonide, which is supposed to cure it. but it only helps for the pain, 4 months now and i use the cream prescribed everyday because it helps with the itchiness and pain, it has not gotten any better. anyone know what else this might be?
