Pain in the opening to the rectum (anus) can be caused by diarrhea or constipation or by scratching a rectal itch. A common cause of anal pain is a tear in the lining of the lower rectum (anal fissure). This type of anal pain usually goes away when the problem clears up. Injury during anal sex or from an object being placed in the rectum also can cause pain. A rare cause of anal pain is spasms of the muscles in the rectum. Some of these conditions may cause some light bleeding.
Home treatment usually can relieve anal pain. If you continue to have anal pain, your doctor may prescribe medicine to relieve pain and other symptoms. Depending on the cause, you may need other treatment.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
