<human>: My husband has a rash (he has been diagnosed with inverse psoriasis but we dont know if this is it) and it has spread all around his torso.  It is not blistering and it is very painful.  It feels like he is being stabbed with a knife at times.  He has seen 2 doctors over the past 4 days and no one knows what it is.  He is using cream for his psoriasis on the rash and the doctor just put him on prednisone hoping that would help.  Nothing seems to be working and it keeps spreading. Any ideas?
<bot>: Hello. Psoriasis is a possible diagnose to consider. There are different types of psoriasis, one of them is inverse psoriasis. Inverse psoriasis, the lesions occurs in large folds:gluteal cleft, inguinal,under the breast, armpits. Initially Lesions have your husband are not in those places. Is very important confirm or exclude diagnose of psoriasis. Psoriasis diagnose disestablished, in many cases, only by symptoms and exploration. It is sometimes necessary additional test such as endoscopy and biopsy. Now prednisone is correct treatment. Improve skin lesions probably, butte most important is established diagnose. If confirmed psoriasis, you must know that is chronic pathology, but there are very effective treatments to treat presently. I wish you good health(In case the answer would have been useful please indicate this)
