I have vitiligo extensively on my legs. For about a year, I underwent the "light therapy", but it didn't help. Now, for over a year and a half, I suffer from a terrible swollen, red, extrememly itchy "rash" that breaks out on the areas only where I have vitiligo, usually in sores. The dermatologist says I have exposed my legs to too much sun, but this past summer, I wore pants religiously, and I still have this terrible looking rash that's painful and itches uncontrollably. Tried cortisone creams, and it helps a little, but nothing will "cure" it. Has anyone else had this problem?
