Anal pain — pain in and around your anus or rectum (perianal region) — is a common complaint. Although most causes of anal pain are benign, the pain itself can be severe because of the many nerve endings in the perianal region.

Many conditions that cause anal pain may also cause rectal bleeding, which is usually more frightening than serious.

The causes of anal pain usually can be easily diagnosed. Anal pain usually can be treated with over-the-counter pain relievers and hot water soaks (sitz baths).

Causes of anal pain include:

• Anal cancer
• Anal fissure (a small tear in the lining of the anal canal)
• Anal fistula (an abnormal channel between the anus or rectum usually to the skin near the anus)
• Anal itching (pruritus ani)
• Anal or rectal stricture (narrowing that may occur from scarring, severe inflammation or cancer)
• Anal sex
• Coccydynia or coccygodynia (tailbone pain)
• Constipation
• Crohn's disease (a type of inflammatory bowel disease)
• Diarrhea (causing anal irritation)
• Fecal impaction (a mass of hardened stool in the rectum due to chronic constipation)
• Genital warts
• Hemorrhoids (swollen and inflamed veins in your anus or rectum)
• Levator ani syndrome (spasm in the muscles that surround the anus)
• Perianal abscess (pus in the deep tissue around the anus)
• Perianal hematoma (a collection of blood in the perianal tissue caused by a ruptured vein, sometimes called an external hemorrhoid)
• Proctalgia fugax (fleeting pain due to rectal muscle spasm)
• Proctitis (inflammation of the lining of the rectum)
• Solitary rectal ulcer syndrome (ulcer of the rectum)
• Thrombosed hemorrhoid (blood clot in a hemorrhoid)
• Trauma
• Ulcerative colitis (a type of inflammatory bowel disease)
• Ulcerative proctitis (a type of inflammatory bowel disease)

Seek immediate medical attention

Have someone drive you to urgent care or the emergency room if you develop:

• A significant amount of rectal bleeding or rectal bleeding that won't stop, particularly if accompanied by lightheadedness, dizziness or feeling faint
• Anal pain that gets much worse, spreads, or is accompanied by fever, chills or anal discharge

Schedule a doctor's visit

Make an appointment with your doctor if your pain lasts more than a few days and self-care remedies aren't helping. Also make an appointment with your doctor if anal pain is accompanied by a change in bowel habit or rectal bleeding.

A hemorrhoid that develops quickly or is particularly painful may have formed a blood clot inside (thrombosed). Removing the clot within the first 48 hours often gives the most relief, so request a timely appointment with your doctor. The blood clot of a thrombosed hemorrhoid, although painful, can't break loose and travel, so it won't cause any of the complications — such as stroke — associated with blood clots that form in other parts of the body.

See your doctor for rectal bleeding, particularly if you're older than 40, to rule out rare but serious conditions such as colon cancer.

Self-care

Depending on the cause of your anal pain, there are some measures you can try at home to get relief. They include:

• Eating more fruits, vegetables and whole grains, exercising daily, and taking stool softeners, if needed, to facilitate bowel movements, reduce straining and ease pain
• Sitting in a tub of hot water up to your hips — known as a sitz bath — several times a day to ease the pain of hemorrhoids, anal fissures or rectal muscle spasms
• Applying over-the-counter hemorrhoid cream for hemorrhoids or hydrocortisone cream for anal fissures
• Taking an over-the-counter pain reliever such as acetaminophen (Tylenol, others), aspirin or ibuprofen (Advil, Motrin IB, others)
