"So I've had psoriasis since 1999 it started after a "precancerous" hpv pap. I've lived with the psoriasis since then with little to no relief with steroid creams. I recently installed a shower head filter which gave me a little relief. I also changed all of my body washes and shampoos to natural and aveno type things that have given me a little relief. Yesterday I seen my Dr and recurved the vaccine for hpv. I woke this morning to shrunken in size not as itchy skin/psoriasis plaques. "
