Does pruritus anus produce r aised itchy bumps, pink skin? Apart I have a anal laceration, a red lump in center of anus, the raised skins are white

Perianal rash. Simple pruritis anus doesn't cause those changes unless there has been repeated trauma from scratching, etc. Lichen sclerosis and atrophicus may be the problem. I recommend an evaluation by a dermatologist for diagnosis and treatment.
