Hello,
HPV warts can effect the area around and inside the anus. They may also affect the skin of the genital area. To confirm the diagnosis and rule out any polyps, get it examined from a surgeon or gastroenterologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Go see a proctologist if you think you have anal warts.
