reduction

I am starting to eliminate taking any Prednisone every other day, 40mg on and 0mg off. As the pic(s) illustrate, some of the ulcer has returned, albeit in a much more mild form. When I shower, I apply Hibiclens (that strange expensive soap in the aqua blue bottle) to the area. It doesn't hurt at all and I know the area is as clean as can be expected. i don't rub or scrub the area because it would cause some bleeding. Its as if my skin is thin, easily damaged.
