I had psoriasis for 5 years. I tried all kinds of topical treatments. The only thing that worked was when I joined a swimming class. I swam for about 30 minutes a day in a chlorine pool. They say psoriasis is stress related at times and thus the exercise probably helped it. Or maybe it was the chlorine. 5 years I had this with bloody feet. It was the worst thing ever. Please try the swimming. It cleared up so fast when I began swimming.
