This Is Why You Get a Stabbing Sharp Pain in Your Butt

A sudden, sharp, stabbing pain in your buttocks can have several causes, ranging from muscle cramps and nerve irritation to conditions like sciatica, hemorrhoids, or even injury. Most often, this pain is not serious, but understanding why it happens helps you know when to seek medical help.

Common Causes of Sharp Buttock Pain

1. Proctalgia Fugax

One of the most overlooked causes of sudden, sharp rectal or buttock pain is a condition called proctalgia fugax. This Latin term literally means “fleeting rectal pain.” It describes brief episodes of severe, stabbing pain deep in the rectum or lower buttock area. These episodes usually come on without warning, often at night or while sitting. They last for seconds or minutes, then disappear as quickly as they started.

The exact cause is unknown, but spasms of the muscles around the anus are thought to be responsible. While the pain can be intense, proctalgia fugax is not dangerous and does not cause lasting damage. 1

1. Muscle Cramps or Spasms

Muscle cramps are a frequent reason for sudden, sharp pain. The gluteal muscles (the large muscles in your buttocks) can cramp if you have been sitting in one position for too long, have overexerted yourself, or are dehydrated. When a muscle cramps, it contracts tightly and painfully, usually lasting a few seconds to a few minutes.2

2. Nerve Irritation: Sciatica

Sciatica describes pain caused by irritation or compression of the sciatic nerve, which runs from your lower back, through your buttocks, and down each leg. If this nerve is pinched or inflamed, it can send sharp, shooting pain into one or both buttocks.
Common causes include a herniated disc, spinal stenosis, or even sitting on a hard surface for extended periods.

3. Piriformis Syndrome

The piriformis is a small muscle deep within the buttock. If it becomes tight or spasms, it can press on the sciatic nerve. This leads to pain that feels like a stabbing or burning sensation right in the center of your buttock. Athletes and people who do a lot of sitting are more likely to experience this condition.3

4. Hemorrhoids

Hemorrhoids usually cause itching, burning, or aching; some people describe a sharp, stabbing pain, especially during or after a bowel movement. Other symptoms include bleeding or a lump near the anus.

5. Injury or Trauma

A fall or direct blow to the buttocks can injure muscles, ligaments, or even the tailbone (coccyx). This can trigger sudden, sharp pain, which may be worse when sitting or moving.
Bruising or swelling might also appear if the cause is an injury.

6. Anal Fissures

An anal fissure is a small tear in the lining of the anus. Passing a hard stool or chronic constipation often causes this problem. The pain is usually described as sharp and stabbing, especially during or right after bowel movements.

7. Other Possible Causes

  • Infections: Rarely, an abscess or infection in the area can cause severe pain.
  • Referred Pain: Sometimes pain from the lower back or pelvis can travel to the buttocks.
  • Coccydynia: Pain in the tailbone, often from sitting for long periods.

When to Worry

Most sharp buttock pain will go away on its own. However, you should seek medical advice if you notice:

  • Severe or worsening pain that does not improve
  • Numbness, weakness, or tingling in your legs
  • Loss of control over your bladder or bowels
  • Swelling, redness, or warmth, which could mean infection
  • Unexplained weight loss or fever

How to Relieve Buttock Stabbing Sharp Pain at Home

Most mild buttock pain can be treated at home. Here are simple steps that may help:

  • Rest: Avoid activities that make the pain worse.
  • Ice or Heat: Use an ice pack for the first day or two, then switch to a warm compress.
  • Gentle Stretching: Light stretching of your legs and hips may ease muscle tension.
  • Pain Relief: Over-the-counter pain medications like acetaminophen or ibuprofen may provide relief.
  • Stay Hydrated: Drink plenty of fluids to prevent muscle cramps.
  • Change Positions: Avoid sitting for long periods. Try to stand up and walk around every hour.

How Doctors Diagnose the Cause

If you see a doctor, they will take a medical history and do a physical exam. Sometimes, imaging tests like X-rays or MRI scans are needed, especially if the pain is severe or lasts longer than a few days.
Your doctor will check for signs of nerve involvement, muscle injury, or other underlying conditions.

How Is Buttock Pain Treated?

Treatment depends on the cause:

  • Muscle-related pain: Physical therapy, stretching, and rest.
  • Nerve pain (sciatica or piriformis syndrome): Anti-inflammatory medications, physical therapy, and in some cases, steroid injections.
  • Hemorrhoids or fissures: Creams, sitz baths, dietary changes to soften stools.
  • Injury: Ice, rest, and sometimes supportive cushions.
  • Infection or abscess: May need antibiotics or minor surgery.

Most people recover fully with simple measures. Persistent or severe pain may require a specialist’s care.

Preventing Buttock Pain

  • Stay Active: Regular exercise keeps your muscles strong and flexible.
  • Watch Your Posture: Sit up straight and use supportive chairs.
  • Take Breaks: Stand and stretch every hour if you have a desk job.
  • Hydrate: Drink enough water throughout the day.
  • Eat a Fiber-Rich Diet: Prevent constipation and avoid straining.

Takeaway

A stabbing pain in your buttock can be startling, but most causes are not dangerous. Muscle cramps, nerve irritation, hemorrhoids, or minor injuries are the usual suspects. Simple home remedies can often bring relief.
However, if the pain is severe, lasts longer than a few days, or is accompanied by other concerning symptoms, see a doctor for a full evaluation.
