Key Takeaways
- Piriformis syndrome happens when the piriformis muscle in your buttock irritates the sciatic nerve.
- The main sign is a deep, one-sided buttock ache that gets worse when you sit.
- No scan confirms it. A hands-on exam diagnoses it after ruling out a disc or spine cause.
- A chiropractor treats it with pelvic and lower back adjustments, soft tissue work, rehab exercises and, for stubborn cases, shockwave therapy.
- Loss of bladder or bowel control, or numbness around the groin, needs A&E instead of a clinic visit.
Piriformis syndrome in Singapore shows up in office workers who sit through nine-hour days and long MRT or car commutes. It also hits runners and lifters who load their hips session after session.
What Is Piriformis Syndrome?
The piriformis is a small, pear-shaped muscle that runs from the base of your spine (the sacrum) to the top of your thigh bone. It turns your hip outward and steadies your pelvis each time you walk, climb stairs or shift your weight.
The sciatic nerve passes right beneath it, and in some people it runs through the muscle itself. Once the piriformis tightens or spasms, it squeezes the nerve and sends symptoms down your leg.
Disc-related sciatica irritates the same nerve higher up at the spine. That shared nerve makes the two conditions feel alike at first, and it’s why an exam matters more than guesswork.
Piriformis Syndrome Symptoms
The main piriformis syndrome symptoms are a deep ache on one side of your buttock that gets worse the longer you sit. Sitting holds the piriformis in a shortened position, which adds pressure on the nerve beneath it.
Other signs include:
- Pain, tingling or numbness down the back of your thigh, which can stop at the knee or reach the calf and foot
- Pain climbing stairs, walking uphill or getting out of a car
- Discomfort when you cross your legs or turn your knee and foot outward
- Stiffness or weakness when you rotate your hip, which can make walking feel awkward
- A sore spot in the middle of the buttock that hurts when you press it
- Some relief once you stand up and move around
Lower back pain can appear alongside it, but your buttock tends to hurt more than your back. If your back hurts most, the cause may sit in your spine or a disc instead.
What Causes Piriformis Syndrome?
Prolonged sitting tops the list of piriformis syndrome causes, followed by repetitive hip movement from running, cycling or lifting. Many cases build over weeks of the same habit instead of starting with one injury.
Common causes include:
- Long hours seated: desk days, MRT and car commutes, or long-haul flights where you can’t change position for hours
- A wallet in your back pocket: sitting on it tilts your pelvis and presses into the muscle
- Overuse from sport: running, cycling, and heavy squats or deadlifts load the hip rotators every session (see what causes back pain when running)
- Weak glutes: a weak gluteus medius and maximus leave the piriformis to stabilise your hip on its own
- Uneven hips or a leg length difference: one side of your pelvis sits higher and the piriformis on that side works harder (read more on uneven hips and how to fix them)
- A stiff sacroiliac (SI) joint: stiffness where your spine meets your pelvis changes how your hip moves
- Foot mechanics: flat feet or ankles that roll inward rotate your leg and load the hip
- A fall or direct blow to the buttock
Piriformis Syndrome vs Sciatica: How to Tell Them Apart
Sciatica is a symptom, and piriformis syndrome is one of its causes. Piriformis syndrome pinches the sciatic nerve at the buttock, while disc-related sciatica pinches the nerve root at your lower spine.
Use this piriformis syndrome vs sciatica comparison to see which pattern matches yours:
| Sign | Piriformis syndrome | Sciatica from a slipped disc |
|---|---|---|
| Where pain starts | Deep in one buttock | Lower back, then the buttock and leg |
| Lower back pain | Mild or absent | Common, can be strong |
| Coughing or sneezing | No change | Can spike the leg pain |
| Sitting | Worse on hard seats | Worse when leaning forward |
| Where leg pain stops | Often at the knee | Can run below the knee to the foot |
| MRI | Normal spine | Can show a disc bulge or herniation |
A normal MRI with ongoing buttock and leg pain is a reason to check the piriformis. For nerve-root causes, see our guide to sciatica and how chiropractic care helps. If hip pain sits alongside your leg symptoms, hip pain or slipped disc covers how chiropractors separate the two.
How Piriformis Syndrome Is Diagnosed
No scan confirms piriformis syndrome. Your chiropractor or doctor diagnoses it with a hands-on exam that rules out spine causes first.
The exam covers five checks:
- History: when the pain started, what sitting and activity do to it, and past injuries
- Palpation: pressing on the piriformis to find the tender spot that reproduces your pain
- FAIR test: the standard piriformis syndrome test, which bends, crosses and turns your hip inward (flexion, adduction, internal rotation) to stretch the muscle; buttock pain during the test points toward piriformis syndrome
- Nerve and spine screen: reflexes, strength, sensation and a straight-leg raise to check for a disc
- Imaging if needed: an MRI rules out a disc or other spine problem, though it won’t show piriformis syndrome itself
No single test proves the diagnosis. Your clinician reads the pattern across all five.
How a Chiropractor Treats Piriformis Syndrome
Piriformis syndrome treatment from a chiropractor eases pressure on the sciatic nerve and corrects the joint and movement problems that keep the muscle tight. Your assessment decides the mix, since the same buttock pain can come from a stiff SI joint, weak glutes, flat feet or a disc.
Stretching and painkillers can ease the ache for a few days. The pain returns because the joint or muscle imbalance loading the piriformis is still there, and that imbalance is what chiropractic care targets.
Pelvic and Lower Back Adjustments
Adjustments restore movement to a stiff SI joint or lower spine so the piriformis stops overworking to steady your pelvis. Your chiropractor applies quick, controlled movements to the joints your exam flagged, and can switch to low-force techniques if you prefer.
Your chiropractor screens for fractures, advanced osteoporosis and inflammatory joint conditions before adjusting. Learn how chiropractic adjustments in Singapore work.
Soft Tissue Release for the Piriformis
Direct pressure and release work loosen the piriformis where it presses on the nerve. Your chiropractor holds pressure on trigger points in the muscle and works the surrounding tissue while moving your hip through its range.
The area can feel tender for a day or two afterward. That soreness fades as the muscle settles.
Shockwave Therapy for Stubborn Cases
Shockwave therapy is an option once buttock pain has lingered for months despite adjustments and exercise. A handheld applicator sends acoustic pulses into the muscle, aiming to lower pain sensitivity and prompt tissue repair.
Research on shockwave for piriformis syndrome comes from small studies, so your chiropractor adds it to a plan instead of using it alone. See how shockwave therapy works at our clinics.
Rehab Exercises to Stop It Coming Back
Strengthening your glutes and core takes load off the piriformis over the long term. Your chiropractor sets exercises such as clamshells, side-lying leg raises and bridges, then progresses them as your pain settles.
For runners and lifters, rehab includes load changes that let you keep training around the flare. Read more about functional rehabilitation.
Custom Insoles When Your Feet Drive It
Flat feet or ankles that roll inward can rotate your leg and keep the piriformis tight. If your assessment finds this pattern, custom foot orthotics support your arch and reduce that rotation so your hip stops compensating.
If the Assessment Points to a Disc
Some buttock and leg pain comes from a disc in the lower spine, which changes the treatment. In that case, spinal decompression therapy takes pressure off the disc by stretching the spine in controlled cycles.
Your chiropractor may combine it with other non-surgical disc treatment options.
Piriformis Stretches and Exercises to Try at Home
Piriformis syndrome exercises at home come down to three stretches and one strengthening move. Stop any movement that causes sharp or shooting pain.
- Lying figure-four stretch. Lie on your back with both knees bent. Cross the sore leg’s ankle over the opposite knee, then pull the lower thigh toward your chest until you feel the stretch in your buttock. Hold 30 seconds, 3 times.
- Seated figure-four stretch. Sit tall and rest the sore leg’s ankle on the opposite knee. Lean forward from the hips with a straight back and hold 30 seconds. You can do this in your office chair between meetings.
- Kneeling hip flexor stretch. Kneel on the sore side’s knee with the other foot in front, then push your hips forward until you feel a stretch at the front of the hip. Hold 30 seconds, 3 times.
- Glute bridge. Lie on your back, knees bent, feet flat. Squeeze your glutes and lift your hips until your shoulders, hips and knees form a straight line. Hold 3 seconds, lower, and do 2 sets of 10.

Heat, Ice and Low-Impact Exercise
Heat relaxes a tight piriformis before you stretch, so try a warm pack for 15 to 20 minutes first. Ice for 10 to 15 minutes calms a fresh flare after a long run or a day of sitting.
Swimming and walking on flat ground keep your hips moving without loading the piriformis the way running and cycling do.
Exercises to Avoid During a Flare
The main piriformis syndrome exercises to avoid load deep hip rotation or keep the muscle compressed. Skip these until the pain settles:
- Deep squats and heavy deadlifts
- Long cycling sessions, indoor or outdoor
- Pigeon pose, if it sharpens the leg pain
- Hill running and stair sprints
- Sitting cross-legged or on your wallet
Bring these back one at a time once you can sit for an hour without buttock pain.
Sitting and Sleeping With Piriformis Syndrome
Sit with both feet flat, your wallet out of your back pocket, and a break to stand and walk every 30 to 45 minutes. A firm cushion takes more pressure off the sore side than a soft sofa.
On long-haul flights, pick an aisle seat so you can stand each hour. Set up your desk with this guide to the best sitting posture for desk work.
A good piriformis syndrome sleeping position is on your back with a pillow under your knees, or on your pain-free side with a pillow between your knees. Both positions stop the sore hip from rotating inward overnight.
How Long Does Piriformis Syndrome Last?
Piriformis syndrome can last from a few weeks to several months, depending on how long you’ve had the pain and what’s driving it. Mild cases caught early can settle within weeks of stretching, activity changes and hands-on care, while pain that has built for months takes longer.
If you want to know how to heal piriformis syndrome quickly, three habits help most:
- Starting care early, before the muscle has guarded for months
- Doing your home exercises between visits
- Changing the trigger: sitting breaks, wallet out, and lower training load for a few weeks
When to See a Chiropractor for Piriformis Syndrome
See a chiropractor if buttock or leg pain hasn’t eased after two weeks of home care, or keeps returning each time you sit for long.
Book an assessment if you notice:
- Tingling or numbness spreading further down your leg
- Pain that wakes you at night
- You can’t sit through a meeting, commute or flight without shifting
- Pain returning each time you restart running or lifting
- A normal MRI but ongoing buttock pain
A chiropractor for piriformis syndrome at Live Well Chiropractic can run the FAIR test and a spine screen in your first visit to work out whether the piriformis, a joint or a disc is behind your pain. Clinics in Bedok, Sengkang, Toa Payoh and Potong Pasir offer same-day assessment.
When to Go to A&E Instead
Go to A&E if buttock or leg pain comes with any of these signs, since they point to nerve compression that needs urgent medical care:
- Loss of bladder or bowel control, or new trouble passing urine
- Numbness in the groin, genitals or inner thighs
- Leg weakness that gets worse over hours or days
- Fever or unexplained weight loss alongside back pain

Frequently Asked Questions
Can a chiropractor help with piriformis syndrome?
Yes, a chiropractor can help with piriformis syndrome by freeing a stiff pelvis or lower back, releasing the tight muscle and setting exercises that stop it tightening again. The first visit also rules out a disc, which decides whether piriformis care is the right plan.
Is walking good for piriformis syndrome?
Yes, walking is good for piriformis syndrome on flat ground, since it moves the hip without the compression of sitting. Hills and stairs load the piriformis harder, so keep to flat routes until the pain settles and stop if leg symptoms spread.
Can you run with piriformis syndrome?
Yes, you can run with piriformis syndrome in many cases if you cut the load that flares it: shorter, flatter runs and no hill or stair sprints for a few weeks. Running with piriformis syndrome through sharp or spreading leg pain can prolong the flare, so a chiropractor can set a return-to-running plan.
Can piriformis syndrome be cured?
Piriformis syndrome can be cured in many cases once you remove the trigger and treat the joint or muscle imbalance behind it. Mild cases can go away on their own, while pain lasting beyond a few weeks tends to return until you address that cause.
Can piriformis syndrome cause back pain?
Yes, piriformis syndrome can cause back pain low in the back near the buttock, as the tight muscle pulls on the pelvis and SI joint. Strong pain higher in the lower back points more toward a spine or disc cause.
Does massage help piriformis syndrome?
Yes, massage can help piriformis syndrome by easing tension in the tight muscle. Massage for piriformis syndrome gives longer-lasting relief when you pair it with joint work and glute strengthening, since those address what keeps the muscle tight.
Can piriformis syndrome cause constipation?
No, piriformis syndrome isn’t a known cause of constipation. New bowel or bladder changes alongside back, buttock or leg pain need A&E, because they can signal pressure on the nerves at the base of the spine.
When is surgery for piriformis syndrome needed?
Surgery for piriformis syndrome comes up after months of conservative care and injections haven’t helped, and many people never reach that point. If your pain persists despite consistent care, your chiropractor can refer you to a doctor to discuss injection or surgical options.
