I have developed a patchy rash on my face. It disappears completely with strong steroid cream but comes back once the cream discontinues. My GP says he hasn't seen it before and has referred me to a dermatologist but that appointment could take months. I think having researched on Google that it is Sebhorrheic Dermatitis. It makes sense as it is more prevalent in people with reduced immune systems and I have been on 6MP for a few months now. This hideous picture shows the rash and where it is. Does anyone have any experience of this? I am going to ask my GP if I can try Nizoral cream as I'm not keen on strong steroid cream until an appointment comes through!
