Shooting pains in the buttocks or rectal area are almost always caused by either a muscle spasm or a compressed nerve, and both are treatable. The fix depends on where exactly the pain hits, how long it lasts, and what triggers it. A sharp jolt deep in the rectum that vanishes within seconds points to a different problem than pain that radiates down your leg when you sit. Here’s how to figure out what’s going on and what actually helps.
Figure Out What’s Causing the Pain
Shooting pains in the buttocks fall into a few distinct patterns, and recognizing yours narrows down the cause fast.
Brief, intense rectal spasms (proctalgia fugax): These feel like a sudden cramp or stabbing pain deep inside the rectum. Episodes last anywhere from a few seconds to 30 minutes, then disappear completely. They’re caused by involuntary spasms of the anal sphincter muscles or nearby pelvic floor muscles. They often strike at night and can wake you from sleep. There’s usually no obvious trigger, though stress and constipation are commonly reported.
A dull ache with sharp flare-ups (levator ani syndrome): This is a similar muscle-based problem, but the pain lingers longer and sits higher up in the pelvis. It often feels like constant pressure in the rectum with occasional shooting pains layered on top. Sitting for long periods tends to make it worse.
Pain that shoots down your leg (piriformis syndrome or sciatica): If the shooting pain starts in your buttock and travels down the back of your thigh, a nerve is likely involved. Piriformis syndrome happens when a small muscle deep in the buttock compresses the sciatic nerve. It feels a lot like sciatica from a spinal disc problem, but the pain is more localized to the buttock rather than starting in the lower back. True sciatica from a herniated disc or spinal narrowing typically begins in the lower back and radiates downward through the buttock and leg.
Pain that worsens with sitting (pudendal neuralgia): The pudendal nerve runs through the pelvis and can become compressed or irritated. The hallmark is pain in the rectal, genital, or perineal area that gets worse when sitting and improves when standing or lying down. Notably, this type of pain does not typically wake you at night.
Tailbone pain (coccydynia): If the shooting pain centers around your tailbone, especially when you sit down or stand up, the coccyx itself may be bruised, misaligned, or inflamed. This is common after a fall, prolonged sitting on hard surfaces, or childbirth.
Stretches That Relieve Nerve-Related Pain
If your shooting pain involves the sciatic nerve or piriformis muscle, targeted stretching can take pressure off the nerve and provide noticeable relief. Do each stretch on both sides, three times per side, twice a day.
- Knee-to-opposite-shoulder stretch: Lie on your back with legs straight. Lift your affected leg, bend the knee, and use the opposite hand to pull the knee toward the opposite shoulder. Hold for 30 seconds.
- Ankle-over-knee stretch: Lie on your back with both knees bent. Cross the ankle of the affected side over the opposite knee. Grab the back of your thigh behind that opposite knee and gently pull it toward your chest. Hold for 30 seconds. You can also do this seated in a chair by crossing your ankle over the opposite knee, letting the knee fall outward, and leaning forward until you feel the stretch in your buttock.
- Glute bridge: Lie on your back with both knees bent and feet flat on the floor. Tighten your core, lift your hips, and squeeze your glutes at the top. Slowly lower back down. Do three sets of 10 repetitions, once or twice a day. This strengthens the muscles that support the pelvis and takes strain off the nerve over time.
These stretches target the piriformis and surrounding deep gluteal muscles. They won’t help with rectal spasms or tailbone pain, so matching the stretch to the right cause matters.
How to Stop Rectal Muscle Spasms
Proctalgia fugax episodes are notoriously hard to treat in the moment because they come on suddenly and often resolve before you can do anything. But there are strategies that shorten episodes and reduce how often they happen.
During an episode, a warm bath or applying gentle heat to the area can relax the anal sphincter and ease the spasm. Some people find that sitting on a warm surface or using a heating pad helps. Slow, deep breathing and consciously trying to relax the pelvic floor can also shorten the cramping.
For prevention, keeping stools soft and regular reduces strain on the pelvic floor muscles. That means adequate fiber, enough water, and avoiding prolonged straining during bowel movements. Stress management also plays a role, since tension tends to tighten pelvic floor muscles.
If episodes are frequent or severe, a topical cream that relaxes smooth muscle can be prescribed. Applied twice daily, it helps reduce the tone of the anal sphincter and can prevent spasms from occurring. This is typically a 2% formulation that you apply in a small amount to the affected area.
Pelvic Floor Therapy for Chronic Pain
When shooting pains keep recurring, especially with levator ani syndrome or pudendal neuralgia, pelvic floor physical therapy is one of the most effective treatments. This isn’t standard physical therapy. It involves techniques specifically designed for the muscles and nerves of the pelvic region.
Myofascial release targets tight “trigger points” in the levator ani and other pelvic floor muscles using specialized massage. This breaks up the tension patterns that cause spasms and referred pain. Biofeedback therapy uses sensors to help you learn how to consciously relax your pelvic floor muscles, which most people can’t do intuitively. Stretching exercises for the lower back, pelvis, and pelvic floor round out the approach. For most people, a combination of physical therapy and medication significantly eases symptoms.
Sitting Modifications That Help
If your pain gets worse when sitting, changing how you sit can make a real difference. For tailbone pain, a U-shaped cushion or a modified wedge-shaped cushion takes pressure off the coccyx by leaving a gap where the tailbone would normally contact the seat. These are inexpensive and widely available.
For pudendal neuralgia, the same principle applies. Avoid hard, flat seats. Stand periodically if you work at a desk. Some people find that sitting on an exercise ball engages different muscles and shifts pressure away from the affected nerve. Even small changes, like tilting your pelvis slightly forward when seated, can reduce nerve compression.
When Shooting Pain Needs Medical Attention
Most shooting pains in the buttocks are benign and manageable, but certain accompanying symptoms change the picture. Rectal bleeding that persists for more than a couple of weeks warrants investigation, particularly because it’s sometimes the earliest sign of a colorectal problem and can precede other symptoms by one to two years. Unexplained weight loss, a persistent change in bowel habits, or a feeling that you can’t fully empty your bowels (tenesmus) alongside rectal pain should prompt a medical evaluation.
For nerve-related pain that hasn’t responded to stretching, physical therapy, or other conservative measures over several months, surgical decompression of the pudendal nerve is an option. In one study of patients who underwent the procedure, 50% reported significant improvement and another 43.5% reported moderate improvement. By the 12-month follow-up, 71.5% of available patients had achieved significant relief. Surgery is typically reserved for cases where other approaches have failed, but the outcomes suggest it’s worth discussing if your pain has become chronic and debilitating.
