Why Does Your Asshole Hurt? Root Causes Explained

Anal pain is surprisingly common, affecting about 1 in 5 people at some point. Most causes are not dangerous, but they can be very uncomfortable. The most frequent reasons include hemorrhoids, anal fissures, muscle spasms, and skin irritation.

What Causes Hemorrhoids and How Do I Know If I Have Them?

Hemorrhoids are swollen blood vessels inside or around your anus. They are the most common cause of anal pain. Research published in the World Journal of Gastroenterology estimates that up to 75% of adults will have hemorrhoids at some point in their lives.

Internal hemorrhoids usually do not hurt. They cause painless bleeding — bright red blood on toilet paper or in the bowl. External hemorrhoids are the ones that hurt. When a blood clot forms inside an external hemorrhoid, it becomes a thrombosed hemorrhoid. That is the hard, swollen, purple lump that hurts intensely.

Straining during bowel movements is the main cause. Sitting on the toilet for too long, chronic constipation, and pregnancy also increase your risk. You can often feel external hemorrhoids as a lump near your anus. The pain from a thrombosed hemorrhoid is worst in the first 48 hours and then slowly improves.

What Is an Anal Fissure and Why Is It So Painful?

An anal fissure is a small tear in the thin skin lining your anal canal. It is one of the most painful conditions in this area. The pain is sharp and burning, and it happens during and after bowel movements.

Passing a hard or large stool is the usual cause. The skin stretches too much and tears. Once the tear happens, the muscle underneath can go into spasm. That spasm keeps the tear from healing and causes more pain. It becomes a cycle — pain causes spasm, spasm causes more pain.

Blood on the toilet paper is common with fissures, just like hemorrhoids. But the pain pattern is different. Fissure pain is directly tied to having a bowel movement. The pain usually lasts from a few minutes to several hours after you go. The American Society of Colon and Rectal Surgeons notes that most fissures heal on their own within a few weeks with simple care.

Why Does Your Asshole Hurt From Muscle Spasms?

Sometimes the pain comes from the muscle itself. The anal sphincter is a ring of muscle that keeps your anus closed. It can go into sudden, intense spasm. This is called proctalgia fugax.

The pain from proctalgia fugax is sharp and stabbing. It comes out of nowhere. It lasts for a few seconds to a few minutes. Then it disappears completely. Some people describe it as a charley horse in the wrong place.

Doctors do not fully understand why this happens. Some studies suggest it may be related to stress or muscle tension. It is not dangerous. It is just very painful for a short time. If the spasm lasts longer, it may be related to pelvic floor tension. That is a different condition that needs a specialist to diagnose.

What About Skin Conditions and Infections?

Your anal area has sensitive skin that can get irritated easily. Eczema, psoriasis, and contact dermatitis can all cause itching and pain. The pain is usually more of a burning or raw feeling rather than sharp pain.

Wiping too hard with dry toilet paper is a common cause of irritation. So is using scented wipes, soaps, or creams. The skin gets red, raw, and painful. Stopping the irritant usually fixes the problem within a few days.

An anal abscess is a more serious cause. It is a pocket of infected pus near your anus. The pain is constant, throbbing, and gets worse over time. You may also have swelling, redness, and fever. An abscess needs medical treatment — usually drainage by a doctor. It does not go away on its own.

A pilonidal cyst can also cause pain near the tailbone. It is a small tunnel in the skin at the top of the buttock crease. When it gets infected, it hurts. It is more common in young men and people who sit for long periods.

When Should You See a Doctor About Anal Pain?

Most anal pain gets better on its own within a few days. But some signs mean you need to see a doctor. The table below helps you decide.

If you have bright red blood and your bowel movements have changed, mention it to your doctor. The CDC recommends regular colorectal cancer screening starting at age 45. Anal pain alone is rarely cancer, but it is worth checking if you have other symptoms.

Do not be embarrassed. Doctors see anal problems every day. They are not shocked or bothered by it. They just want to help you feel better.

What Actually Helps Anal Pain at Home?

Simple things work well for most causes of anal pain. Warm water is one of the best treatments. A sitz bath — sitting in a few inches of warm water — relaxes the muscle and cleans the area. Do it for 15 to 20 minutes after bowel movements. You can do it two to three times a day.

Softening your stool is key. Drink more water. Eat more fiber from fruits, vegetables, and whole grains. The Academy of Nutrition and Dietetics recommends 25 to 38 grams of fiber per day. If you cannot get that from food, a fiber supplement like psyllium husk can help. Stool softeners like docusate are another option, but fiber is better long-term.

Some things to avoid:

• Do not strain on the toilet. If you cannot go, get up and try later.
• Do not sit on the toilet for more than 5 to 10 minutes. It puts pressure on the area.
• Do not use scented wipes or harsh soaps. Plain water is best.
• Do not sit for hours without moving. Get up and walk around.

Over-the-counter creams with hydrocortisone can help with itching and swelling. Use them for no more than a week. Longer use can thin the skin. Pain relievers like ibuprofen or acetaminophen can help with general discomfort.

For muscle spasms, warm baths and gentle pressure on the area sometimes help. Some people find that a cold pack wrapped in a cloth helps more than heat. Try both and see which works for you.

If you have a thrombosed hemorrhoid, the pain is usually worst for the first two days. It then gets better over the next week. The clot may break down on its own. If the pain is unbearable, a doctor can remove the clot in a quick office procedure.

Common Misconceptions About Anal Pain

Many people think anal pain means something serious like cancer. That is almost never the case. Colorectal cancer rarely causes pain until it is advanced. Pain is much more likely from the conditions described above.

Another common belief is that spicy food causes anal pain. This is widely claimed, but strong evidence is limited. Spicy food can make existing irritation feel worse. It does not cause hemorrhoids or fissures. If you notice a pattern with spicy food, avoid it. But do not assume it is the root cause.

Some people think that if they cannot see the problem, it is not there. Internal hemorrhoids and fissures are inside the anal canal. You cannot see them. The absence of a visible lump does not mean nothing is wrong.

People also believe that anal pain always needs surgery. That is not true. Most cases resolve with simple home care. Surgery is reserved for the small number of cases that do not improve with conservative treatment.
