Before I found out I has psoriasis and PSA, I was told I had Grover's disease. I lived with that for a few years- very mild case - because it is chronic- I looked for alternative solutions and stumbled upon a Chinese Dr in Santa Barbara, Ca. I sought him out and began a regimen of bulk herbs which are VERY potent. It was almost completely gone- but my schedule got erratic and then I had surgery and laid off of them. I had prednisone in that time which led to total clearing. (I didn't know this at the time) but 2 1/2 - 3 months later was the first sign of little bumps on my knee. Came and went- then elbow - same. Had oral surgery and lots of antibiotics during the span of 5months. 4 very stressful months later- I broke out on my hand, chest arms and was baffled. It took a month to get to a derm who said-psoriatic arthritis. I wasn't feeling any particular joint pain...yet! That kicked in two weeks later with a vengeance. I went back to him- opting for the natural route but wasn't able to do it long enough to get a result. I'm curious if anyone else has tried- benefited or failed? They claim 90%cure rate to conventional medicine 70%.
