Same problem here, ive tried shark cartilage, high doses vit d (what tanning does) high doses fish oil. The ONLY thing that fixed mine, with no flare ups was when i dieted and cut my carbs completely out. My hair line and ears cleared up along with all the spots on my body! The medicine (topical) if you read the labels all convert to vit d after soaking through the skin. Tanning also clear mine up.. i had to start doing it again. Since i started "bulking" ie; adding a lot more carbs ive had huge breakouts, and my scalp is crazy bad! My moms from the phillipines, and never had a single spot on her body until she came to the states, now shes the worst patient theyve seen at out hospital with psoraisis (covers 98%) of her body. Shes using stalara now (from the commercials) and its almost all gone.... just my two cents. Oh and my two brothers have it as well...
