Larger papule-like bumps embedded in the skin are called nodules, while larger, pus-filled lumps are called cysts. There are different types of pimples, including pustules, which are small raised pink or red bumps that contain pus. Of course, it’s possible that what you suspect to be a pimple is in fact just an ordinary pimple on your anus. The bump you feel may also be a different health concern, including a hemorrhoid or a cyst that will require treatment by a healthcare professional. That can lead to infection and other complications. If you notice what appears to be an anal pimple, don’t pick at it. In the anus, pimples are different from anal warts, which are caused by HPV and can grow large. Pimples can form on many areas of the body, including the face, back, pubic area, and even the anus.
