[|Human|] Hi! I have extremely dry skin where my two butt cheeks meet, like in the crack of my butt. It itches terribly, and often leaves a burn of flakey dry skin in my underwear. I know that I have psoriasis on my scalp. I was just wondering if it can affect my butt cheeks and also my genital area? I ve had vaginal itch since I was young. Yeast infection medicines dont work, rarely will an anti-itch cream work. It was localized on one side of my vagina for 10 years and had since spread to both sides. My family doctor just says to use anti-itch, but I think there s a bigger issue or a better answer. The left (original) side had turned a darker color and is thicker. What exactly could be the issue?
[|AI|]  Hello and welcome to Chat Doctor Psoriasis is a likely possibility as it can very well involve the body folds. Psoriasis classically involves the extensors like scalp, elbows, knee, shins and lower back, but sites like maxilla, groin folds can also be involved either together with the extensors or solely, where it is classically known as inverse psoriasis would advise that you see a dermatologist for a confirmatory diagnosis. Psoriasis in the body folds responds very well to topical steroids as well as topical immunomodulators like tacrolimus/pimecrolimus ointment. An OTC antihistamine once daily e.g. cetirizine would help you symptomatically with the itch. Regards
