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?
