I recently had three warts on my penis treated with Trichloroacetic Acid, one of them seems to be what I would expect to be reacting normally, eg: becoming darker in color only on the affected area. The two others are drastically darker in color, and the area surrounding the warts is also appearing very dark and spreads approximately 1/2 " away from the warts themselves. Is this a typical reaction or should I follow up with my physician?
