I have small little white hard bumps on the inside of my anus and they itch... what should i do?

Go to your doctor: See your primary care doctor for evaluation, diagnosis and possible treatment.

Perianal warts?: Possibly viral warts . Need to be diagnosed by experienced physician. Difficult to treat. May be treatable by anti viral vaccine for human papilloma virus. Vaccine is not mainstream, but viral warts are a common problem. Doctors usually burn or laser them off. No one very happy with the treatment or results.. Could do with lots of opinions from experienced docs.
