A sore butt usually comes down to one of a few things: muscle strain from exercise, too much time sitting on a hard surface, or irritation of a nerve or bursa deep in the glute. Less commonly, it can signal a skin issue like a cyst or abscess, or pain radiating from the tailbone. Most causes resolve on their own or with simple changes, but the location and type of soreness can help you figure out what’s going on.
Post-Workout Muscle Soreness
If you recently did squats, lunges, deadlifts, hill sprints, or any lower-body workout you’re not used to, your glutes are probably just dealing with delayed onset muscle soreness (DOMS). This type of soreness starts 12 to 24 hours after exercise and peaks between 24 and 72 hours. It feels like a deep, dull ache that gets worse when you sit down, stand up, or use the muscle. DOMS settles on its own after a few days and doesn’t need treatment beyond gentle movement, light stretching, and time.
A true muscle strain feels different. You can usually pinpoint the pain to one specific spot, and you may remember the exact moment it happened. A mild strain heals within a few weeks. A moderate strain can take several weeks to months. Severe tears, which are rare in the glutes, can require surgery and four to six months of recovery. If the pain came on suddenly during activity, feels sharp rather than achy, or the muscle feels weak, you’re likely dealing with a strain rather than normal post-workout soreness.
Pain From Prolonged Sitting
Sitting for long stretches, especially on hard or narrow surfaces, is one of the most common reasons for unexplained butt soreness. The culprit is often ischial bursitis, sometimes called “weaver’s bottom” because it historically affected people who sat on hard benches all day. Your sit bones (the bony points at the base of your pelvis) have small fluid-filled sacs called bursae that cushion them from the overlying muscle. When those sacs get inflamed from sustained pressure, the result is a low-grade, pinpoint aching sensation right where your weight lands on a chair.
The pain typically gets worse with more sitting, climbing stairs, or stretching the glute. Some people also notice it radiating into the upper back of the thigh. Trouble sleeping on that side, stiffness when standing up from a chair, and mild swelling around the sit bone are also common. The fix starts with reducing the aggravating pressure: stand and walk more often, avoid hard chairs, and consider a memory foam seat cushion designed to offload the sit bones. Cushions with cutouts or contoured shapes specifically redistribute weight away from the bony contact points. If the pain lingers for more than a couple of weeks despite these changes, physical therapy can help.
Piriformis Syndrome and Nerve Pain
The piriformis is a small, deep muscle that runs across each buttock from the base of the spine to the top of the thighbone. The sciatic nerve passes right next to it, and in some people, directly through it. When the piriformis tightens or spasms, it can compress the nerve and produce a deep, burning or tingling pain in one buttock that sometimes shoots down the back of the leg.
This feels a lot like sciatica caused by a disc problem in the lower back, but the key difference is location. Piriformis syndrome produces pain in a more specific area of the buttock, while disc-related sciatica tends to start in the lower back and radiate downward. Piriformis pain often flares with sitting, crossing your legs, or climbing stairs.
Stretching and strengthening exercises are the primary treatment. A few that target the piriformis directly:
- Knee-to-opposite-shoulder stretch: Lie on your back, bend one knee, and use the opposite hand to pull it toward the opposite shoulder. Hold 30 seconds, repeat three times on each side.
- Ankle-over-knee stretch: Lie on your back with both knees bent. Cross one ankle over the opposite knee, then gently pull the bottom thigh toward your chest. Hold 30 seconds, three times per side. You can also do this seated in a chair by crossing your ankle over the opposite knee and leaning forward.
- Clamshells: Lie on your side with knees bent in an L-shape. Keeping your heels together, lift the top knee like opening a clamshell. Do 10 reps on each side, three sets.
- Bridges: Lie on your back with knees bent, tighten your core, and lift your hips. Squeeze your glutes at the top. Lower slowly. Do 10 reps, three sets.
Walking and using an elliptical are good low-impact cardio options that keep the hip muscles active without aggravating the nerve.
Tailbone Pain
If the soreness is centered low and midline, right at the base of your spine rather than in the fleshy part of the buttock, the issue may be your coccyx (tailbone). Tailbone pain, or coccydynia, commonly follows a fall or impact directly onto the area. It can also develop from sitting on hard or narrow surfaces for extended periods, from joint changes due to arthritis, or during and after childbirth. The pain is usually sharp or aching when you sit and eases when you stand or walk. Leaning back in a chair tends to make it worse. A wedge-shaped or coccyx-cutout cushion helps by keeping pressure off the tailbone while you sit.
Skin Issues: Cysts and Abscesses
Sometimes the pain isn’t deep in the muscle at all. A perianal abscess feels like a swollen, tender boil near the edge of the anus, often red, constantly throbbing, and painful enough to make sitting, coughing, and using the bathroom miserable. You may notice pus-like discharge, a visible lump, or in some cases, fever and chills. An infected cyst in the same area tends to be less painful and less likely to cause fever, but it still creates a noticeable, sore lump. These conditions don’t resolve with stretching or cushions. An abscess typically needs to be drained by a healthcare provider, and infected cysts may need similar treatment.
Practical Relief for General Glute Soreness
When the soreness is mild and you’re not sure of the exact cause, a few simple strategies cover most of the common culprits. Ice the area for 15 to 20 minutes at a time during the first couple of days if there’s any swelling or acute pain. After that, gentle heat can help relax tight muscles. Break up long sitting periods by standing or walking for a few minutes every 30 to 60 minutes. A firm but cushioned seat surface is better than either a very hard chair or a very soft couch, which can let your sit bones sink and bear more load.
The stretches listed above for piriformis syndrome also work well for general glute tightness. Side leg lifts and small-range squats build strength in the muscles that stabilize the hip, which reduces the load on any single structure. Aim for three sets of 10 reps, once or twice a day.
Signs That Need Urgent Attention
Most butt soreness is not dangerous, but a specific cluster of symptoms points to a rare condition called cauda equina syndrome, where the bundle of nerves at the base of the spinal cord is compressed. Warning signs include numbness spreading across the buttocks, inner thighs, or groin (sometimes called “saddle numbness”), sudden difficulty urinating or having a bowel movement, new loss of bladder or bowel control, and leg weakness that makes walking difficult. These symptoms together are a medical emergency. If you notice them, go to an emergency room immediately, as delayed treatment can cause permanent nerve damage.
