Pain in the buttock muscles usually comes from one of a handful of causes: a strained muscle, a tight or inflamed piriformis pressing on a nerve, irritation in the tendons that attach your glutes to the hip, or dysfunction in the joint where your spine meets your pelvis. The good news is that most of these resolve on their own or with simple stretches and activity changes. Understanding which type of pain you’re dealing with helps you figure out what to do next.
Muscles That Can Cause Buttock Pain
Your buttock is made up of three layered muscles: the gluteus maximus (the large, outermost muscle you sit on), the gluteus medius (which wraps around the side of your hip), and the gluteus minimus (the smallest, deepest layer). Beneath all three sits the piriformis, a small, flat muscle that runs diagonally from your lower spine to the top of your thighbone. These muscles work together every time you walk, climb stairs, stand up from a chair, or shift your weight from one leg to the other.
Pain can originate in any of these muscles, but it can also be referred from nearby structures like the sacroiliac joint or the sciatic nerve. That overlap is part of what makes buttock pain tricky to pin down on your own.
Gluteal Muscle Strain
The most straightforward explanation for sore butt muscles is a strain, meaning you’ve overstretched or torn some of the muscle fibers. This often happens during exercise, heavy lifting, sudden sprints, or even long periods of sitting followed by abrupt activity. A strained glute typically feels like a deep, localized ache that gets worse when you squeeze the muscle, sit down, or push off while walking.
Strains are graded by severity. A mild (grade 1) strain involves minor fiber damage and generally heals within one to three weeks with rest and gentle movement. A moderate (grade 2) tear, where a larger portion of the muscle is damaged, takes four to eight weeks of structured rehabilitation including progressive strengthening. A severe (grade 3) rupture, where the muscle is completely torn, can require three to six months of recovery and sometimes surgery.
Most people dealing with buttock soreness after a workout, a long car ride, or a new physical activity are in grade 1 territory. If you can still walk and the pain is more annoying than sharp, rest and stretching are usually enough.
Piriformis Syndrome
The piriformis muscle sits directly on top of the sciatic nerve in most people. When it gets tight, swollen, or spasms, it can compress that nerve and produce pain that feels deeper and more electric than a regular muscle ache. People with piriformis syndrome describe the sensation as aching, burning, tingling, numbness, or shooting pain in the buttock, hip, or upper leg. The pain can travel down the back of the leg, which is why it’s often confused with sciatica.
The key difference: sciatica caused by a herniated disc or spinal stenosis tends to start in the lower back and radiate through the buttock and down the leg. Piriformis syndrome stays more focused in the buttock itself, since the compression happens in one specific spot rather than at the spine. Both affect the sciatic nerve, but the source of the pinch is different.
About 13% of the population has an anatomical variation where the sciatic nerve passes through the piriformis muscle rather than beneath it. If you’re in that group, you may be more prone to piriformis-related pain, especially during repetitive activities like running or prolonged sitting.
Gluteal Tendinopathy
If your pain is concentrated on the outside of your hip and extends down toward your knee, the problem may not be the muscle itself but the tendons that anchor your glute muscles to the top of your thighbone. Gluteal tendinopathy develops when those tendons become irritated or partially damaged, often from repetitive loading or a sudden increase in activity. It’s especially common in runners, walkers, and people who spend a lot of time on their feet.
The hallmark sign is pain at the bony point on the outside of your upper thigh, an area called the greater trochanter. It often feels tender to touch and gets noticeably worse when you stand on one leg, even for something as simple as pulling on a pair of pants. You might also feel it in the lower back, groin, or deep in the buttock. An MRI or ultrasound can confirm tendon damage, but many providers diagnose it based on symptoms and a physical exam alone.
Sacroiliac Joint Dysfunction
The sacroiliac (SI) joint sits right where the base of your spine meets your pelvis, on each side of your lower back. It doesn’t move much, but it absorbs and transfers force between your upper body and legs with every step. When the ligaments, joint surfaces, or surrounding muscles aren’t working in sync, the joint can become irritated and refer pain into the buttock.
SI joint pain is notoriously difficult to diagnose because the nerve pathways overlap with so many other structures in the region. It tends to feel like a dull ache deep in one side of the buttock or lower back, often worse after sitting for a long time, rolling over in bed, or transitioning from sitting to standing. Unlike piriformis syndrome, it rarely produces the tingling or burning sensations associated with nerve compression.
Muscle vs. Nerve Pain: How to Tell the Difference
The type of sensation you feel is the biggest clue. Muscle pain tends to be a dull, sore ache that worsens when you use the muscle and improves with rest. It usually stays in one area and responds to pressure, like when you sit on a tennis ball or foam roller. Nerve-related pain is different: it burns, tingles, shoots, or causes numbness, and it can radiate well beyond where the problem actually is. If your pain travels down the back of your leg or you notice tingling in your foot, a nerve is likely involved.
Pain that only shows up after exercise and fades within a day or two is almost always muscular. Pain that lingers regardless of activity, wakes you up at night, or comes with weakness in your leg warrants closer attention.
Stretches That Help
Holding a stretch for at least 30 seconds, performed three to five times per week after a brief warm-up, is one of the most effective ways to relieve buttock pain from muscular causes. Harvard Health recommends three specific stretches:
Kneeling hip flexor stretch: Kneel with your right leg in front, knee bent at 90 degrees, foot flat on the floor. Place your hands on your right thigh and lean forward, pressing your left hip toward the floor. You should feel the stretch in the front of your left thigh and hip. Hold for 30 seconds, then switch sides.
Single knee pull: Lie on your back with legs extended. Bend one knee, grasp the back of your thigh, and pull it toward your chest until you feel the stretch in your lower back and buttock. At the same time, press the opposite leg flat against the floor. Hold, then switch.
Floor pretzel: Lie on your back with one knee bent and foot flat on the floor. Rest the opposite ankle on that thigh just above the knee. Grasp the back of the bent thigh with both hands and slowly lift that foot off the floor. You’ll feel this deep in the hip and buttock of the crossed leg. This is particularly effective for piriformis tightness.
Other Common Culprits
Prolonged sitting is one of the most underestimated causes of buttock pain. Sitting for hours compresses the glute muscles and reduces blood flow, which can leave them stiff, sore, and weak over time. If your pain consistently appears after long stretches at a desk or in a car, simply standing and walking for a few minutes every 30 to 60 minutes can make a meaningful difference.
Delayed onset muscle soreness (DOMS) from squats, lunges, deadlifts, or hill running is another frequent cause. This type of soreness peaks 24 to 72 hours after exercise and resolves on its own. It’s a normal response to unfamiliar or intense loading and doesn’t indicate injury. If the soreness is still getting worse after 72 hours or is accompanied by swelling, bruising, or sharp pain with movement, you may be dealing with an actual strain rather than standard post-exercise soreness.
Signs That Need Medical Attention
Most buttock pain is benign and temporary. But certain symptoms point to something more serious. Numbness in the groin or inner thighs (sometimes called saddle anesthesia), sudden loss of bladder or bowel control, or rapidly progressive weakness in one or both legs can indicate pressure on the nerves at the base of the spine and require emergency evaluation. Buttock pain accompanied by fever could indicate an infection in the muscle itself, a rare but potentially dangerous condition.
Pain that persists for more than a few weeks without improvement, gets progressively worse, or significantly limits your ability to walk or sleep is worth getting assessed. Imaging and a physical exam can rule out structural problems and point toward the right treatment approach.
