I have scaling and itching on the back of my leg around my lower thigh and upper calf. As it improves slightly in one spot it seems to migrate down my leg. I have tried moisturizing lotion, cortisone cream, psoriasis cream and tenactin. They all give relief from the itching but do not cure the problem. Thoughts? I wonder if I may have an allergy to Flonase. The time I started taking it would be roughly the same time as the condition started
