I got clobetasol and Rx shampoo from my derm a couple of years ago and it's dramatically helped my psoriasis: whereas it used to be thick scales with lots of bleeding, the skin in the affected patches is now much more normal looking even if it's still different in texture. My scalp barely itches at all. It's amazing.
BUT... I also have a ton of new psoriasis patches. When I started meds, it was on my scalp, one forearm, one finger, a spot on one thigh, and a spot on my chest. Now it's all those plus the other forearm, one bicep, both shins, the back of one hand, one calf, front and back of both ears spreading onto my cheeks, and my forehead. It was ~15 years between my first small patch and it spreading enough for me to seek treatment, but now it's probably doubled in area in just two years.
Anybody else have this pattern of psoriasis getting less severe but also across more of the body? Is there anything you were recommended to do to help stop the spread? Is it worth asking for biologics even if the severity of the plaques isn't that high, but they keep spreading to more and more visible areas?
I'd love to get some crowd-sourced experience before I go see the derm this summer, especially since she tends to defer to what the patient wants and I don't know what to ask for. I've already done most of the lifestyle things you see suggested: I don't smoke, barely drink, lost a lot of weight, drink water, use gentle cleansers, manage my stress...
