Hi there,I have been living with psoriasis since I was about 8. I underwent UV light treatment, and it cleared up for almost 10 years (except little patches here and there). I have always had it on my scalp, but recently I have noticed a patch at the top of my buttocks fold. It has since spread down the fold and around the anus. Very embarrasing, but I am wondering what kinds of treatment or prescription I should seek out to rid this, as it is uncomfortable, and visually horrible. Thanks!
