Genital psoriasis worse after using Dovobet

Hi everyone I've been dealing with scalp psoriasis for the last 3 years and every few months or so, a new small patch will appear on my scalp. In the last few months though, I have developed psoriasis on my vulva. It popped up out of nowhere and what seemed like overnight. I have been treating it with Dovobet cream from my GP and the original patch is almost gone after 2 and a half weeks of use so far but I have noticed that since after about a week of using the cream, I have what I think are new patches on both sides of my vulva now and its red raw and painful. I went to the nurse about it and she said it was irritation from the Dovobet and gave me Epaderm to use along with Dovobet but it is making no difference whatsoever and feels and looks like the exact same first psoriasis patch I had down there but surely psoriasis can't just pop up over the course of a few nights like the new patches or whatever they are have?! Using Dovobet down there was fine until about 4 days into treatment. I am at my wits end and can't get another doc appt until the end of Sept. I do have a phone call appt with the GP tomorrow to see how the cream has helped though. I'm hoping its just irritation after all but its on skin that the cream shouldn't ever be touching. Its painful, I can't wear certain stuff like jeans, it makes me self conscious around my husband when he tries to be affectionate or intimate with me. If anyone else has genital psoriasis, I would love to chat to you as well. Feel so down and alone since this all started :( Also, I do have a local GUM/Sexual Health clinic near by that does walk in appts, would they be able to help? GP did swabs for everything and they all came back fine though. Even though my scalp psoriasis hasn't responded to any treatment and now my genital psoriasis has popped up, I've never once been offered a referral to dermatology. Thanks to anyone who reads this :)
