Yoga guide
Piriformis syndrome means sciatica-type pain from the sciatic nerve being irritated deep in the buttock, near the piriformis muscle. It's real but debated and uncommon: most buttock pain that runs down the leg comes from the back, so it's worth getting assessed. No trial has tested yoga for it, and no treatment has been shown better than another.
What yoga can offer is what the evidence points to: moving often, sitting less, building hip strength and, if they help, gentle stretches. It sits beside care from your GP or physiotherapist, never in place of it.
This guide covers how it differs from sciatica from the spine, the poses that work the glutes hardest, whether pigeon helps, the poses that sit on or squeeze the sore buttock, which classes to follow, and the warning signs that need help.
There's no accepted test. The commonest features are pain deep in the buttock, pain worse sitting, tenderness in the buttock and pain when the muscle is tensed. Between 6% and 17% of people seen in hospital clinics with sciatica meet the criteria for the broader deep gluteal syndrome; most sciatica comes from the back.
We found no trial of yoga for piriformis syndrome. A review of treatments found no conservative treatment better than another, and advises following back pain and sciatica care first: physiotherapy and staying active.
One person's pain went with hip strengthening alone, a single case. In a lab study of young adults, half moon and warrior III worked the buttock muscles hardest of five yoga poses tested.
Stretching trials are small, and combined programmes did better than stretching alone. Pigeon may feel good, but no trial shows it treats piriformis syndrome; stop any stretch that sends pain down your leg.
Break up long spells of sitting, and keep long seated poses short. One case report describes severe piriformis syndrome after three yoga and Pilates sessions in a woman who had been inactive for a year, so build up slowly and don't force deep hip positions.
Sciatica in both legs or numbness around your genitals or bottom needs 999; a swollen, painful calf needs help the same day. The full list is below.
The piriformis runs from the base of your spine to the top of your thigh bone, deep under the buttock muscles. The sciatic nerve usually leaves the pelvis just below it; in a surgical review its path varied in about 16% of people, and the nerve glides about 28 mm as the hip bends. Our piriformis muscle guide has the anatomy.

Across 55 studies, mostly single cases, the commonest features were buttock pain, tenderness near the notch where the nerve leaves the pelvis, pain worse sitting and pain when the muscle is stretched or tensed. An updated review says the accuracy of the tests "cannot be concluded from studies to date". A narrative review calls it "a relatively uncommon, but not insignificant, cause of sciatica".
Many clinicians now use this broader label for sciatic nerve trouble in the buttock that doesn't come from a disc; piriformis syndrome is one form of it. Between 6% and 17% of people seen in hospital clinics with sciatica meet its criteria.
Pain centred deep in the buttock, worse sitting, with tenderness there, points to the buttock; pain below the knee with numbness or weakness, or pain that began with back pain, points to the back. A straight-leg raise doesn't tell them apart, and a lower back scan doesn't show the deep buttock. The NHS has no piriformis page, and its sciatica page doesn't mention it. Get assessed if symptoms persist.
In a small study of 91 people, the piriformis was no thicker in people with the syndrome, and a thicker piriformis went with a weaker gluteus maximus. A case report found weak hip muscles and suggested overstretching rather than tightness. Neither shows what causes it.
Yoga's hip openers (figure four, pigeon, fire log, cow face) bend the hip and turn it out, the classic piriformis stretch positions. Its standing and balancing poses work the buttock muscles. Long seated poses, lotus and cow face sit on, or press into, the sore area.
No trial has tested yoga for piriformis syndrome, so this section draws on the small exercise and stretching trials, lab studies and case reports, and says which is which.
Our searches found two records on yoga and piriformis or deep gluteal syndrome: a case report and a workplace yoga protocol. The treatment reviews list no yoga trial.
A review of 13 studies (508 people), whose randomised trials all tested injections, rated the evidence low: "no single conservative treatment can be recommended over another. Clinicians should follow general guidelines on the management of back pain and sciatica for first line treatment, namely physiotherapy." In 2019, no controlled trial of physiotherapy had been found.
The first review of stretching (12 studies, 572 people, 4 randomised trials) found combined programmes did better than stretching alone, with small samples and little long-term follow-up. In the small trials, both groups usually improved: two stretching techniques in 40 people, two hands-on techniques with stretching in 48, self-stretching against self-compression in 45 (stretching better for disability), and shock wave against dry needling with stretching in 48. None followed people beyond 4 months.
In a scan study of 7 people, two classic stretches lengthened the piriformis by about 12%, and bending the hip further with the knee drawn across the body lengthened it about 15%. In 21 healthy young men, the muscle was stiffest at full outward turn with the hip bent to 110 degrees and drawn across. Pigeon wasn't tested. These were healthy people, not people with the syndrome, so favouring a figure four pulled across over pigeon is our inference.
In 10 people having hip surgery, bending the hip with the knee straight raised strain on the sciatic nerve by about a quarter, and in cadavers, pressure inside the nerve passed harmful levels only with the hip bent and the knee fully straight. So folds over straight legs may provoke an irritated nerve more than bent-knee hip openers; that is our inference, not a trial finding.
In one case report, hip strengthening and movement retraining alone took pain to 0. In 31 healthy adults aged 18 to 35, half moon and warrior III worked the buttock muscles hardest of five yoga poses (the lifted leg's gluteus maximus at about 63% and 46% of its maximum). This supports hip strength as a low-risk focus, not a proven treatment.
Botulinum toxin, anaesthetic and steroid injections eased pain in pooled studies, many of which weren't randomised. They're a later step after exercise and advice, and surgery is for long-standing cases.
One case report describes a 60-year-old woman with severe piriformis syndrome "following three consecutive sessions of yoga and Pilates, an exercise regimen she had recently adopted after being inactive for nearly a year". It names no poses, and she recovered on medicines for nerve pain after physiotherapy and injections hadn't helped. In US emergency departments, hip injuries were a larger share of yoga injuries in people over 45. A single case shows it can happen, not how often.
The NHS sciatica advice applies: start gentle exercise as soon as you can, and don't sit or lie down for long periods. Break up sitting every 30 to 45 minutes, as our piriformis syndrome guide says.

Our editorial starting point: bridges, the belt press, clamshells, chair pose, warrior II and tree pose at a wall, then warrior III and half moon with a wall, 2 or 3 times a week, building over weeks.
Start with the reclined figure four and never press down on the crossed knee. Keep a stretch only if it eases the pain, and stop any stretch that sends pain or tingling down your leg.

See a GP or physiotherapist if leg symptoms persist, spread below the knee or come with numbness or weakness: piriformis syndrome is one of several causes of buttock and leg pain.

Call 999 or go to A&E: loss of feeling or numbness around the genitals or bottom, new trouble peeing or controlling your bladder or bowels, changes in genital sensation during sex or problems with erections or orgasm, or pain, tingling, weakness or numbness in both legs. These are signs of cauda equina syndrome, which needs treating in hospital urgently. Don't drive yourself.
Call 999 or go to A&E if breathing suddenly becomes difficult, if pain in your chest or upper back comes on suddenly with breathlessness or a very fast heartbeat, or if someone passes out. Do not drive yourself. It can be a blood clot that has reached the lungs.
Same day (urgent GP appointment or NHS 111): throbbing pain in one leg (rarely both), usually the calf or thigh; swelling in one leg (rarely both); red, blue or darkened skin around the painful area, which may be harder to see on brown or black skin; or swollen veins. This can be a deep vein thrombosis (DVT). It is more likely after surgery, a hospital stay, 3 or more days in bed, a journey of over 4 hours, pregnancy or a recent birth, cancer, a previous clot, or contraception or hormone replacement therapy (HRT) that contains oestrogen.
Same day: leg weakness that is getting worse.
Same day (urgent GP appointment or NHS 111): new difficulty lifting the front of your foot or toes (foot drop), or a foot that slaps down or catches as you walk, especially if it is getting worse. Weakness in both legs, or with numbness around the genitals or bottom or bladder or bowel changes, is the 999 emergency above.
Same day (GP or NHS 111): back pain and you feel hot, cold, shivery or generally unwell, or severe pain that starts suddenly or is getting worse quickly.
Ask for an urgent GP appointment or get help from NHS 111 if you have severe hip pain that started suddenly but you've not had a fall or injured your hip, your hip is swollen and feels hot, the skin around your hip has changed colour, or you have hip pain, feel generally unwell and have a high temperature (or feel hot, cold or shivery). A hot, swollen hip with a high temperature can be a joint infection.
Sudden mid or lower back pain after a minor fall, lift, cough or sneeze, especially from 50 or with long-term steroid tablets.
Often worse moving or changing position and eased by lying down. It can be an osteoporotic spinal fracture, so see a GP; height loss or a new curve in the upper back are other signs.
Low back, buttock or groin pain in an older person after a minor fall, or with no clear injury, making walking very hard.
This can be a fragility fracture of the sacrum or pelvis, which a plain X-ray can miss: get it checked.
Pain that spreads below the knee with pins and needles, numbness or weakness: read about sciatica and get assessed.
Unexplained weight loss, or a lump, swelling or change in the shape of your back.
Pain that doesn't improve with rest or is worse at night, or pain that is worse when you sneeze, cough or poo.
If your sciatica hasn't improved after a few weeks of looking after it at home, is getting worse, or is stopping you doing your normal activities. In many areas you can refer yourself to NHS physiotherapy for back problems.
Ease out of any stretch that sends pain or tingling down your leg, don't press down on a crossed knee, keep a massage ball moving and off the middle of the buttock, get up and move if a leg goes numb in a long seated or kneeling pose, and build up slowly if you're new to classes (our suggestion).
You can say no to any hands-on adjustment, and a teacher registered with Yoga Alliance must get your explicit consent each time.
If you're hypermobile, don't use mobility work to push further: the NHS says "do not overextend your joints just because you can". See a GP if you think you have joint hypermobility syndrome: for example, your joints keep dislocating, or you keep getting sprains, strains, pain or stiffness.
A joint pain that is sharp, gets worse during a session, lingers into the next day or changes how you move is a reason to use an easier version, and to see a GP or physiotherapist if it keeps happening (the rule in our plans). Muscle soreness for a day or two after something new is normal. In a hot class, stop if you feel dizzy, sick or unwell; our hot yoga guide lists the signs of heat illness.
Call 999 if:
The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.
No trial has tested pigeon, or any yoga, for it, and no treatment has been shown better than another. In the lab, other hip positions lengthened the piriformis more. Pigeon may feel good; stop it if it brings on leg symptoms or knee pain.
It's uncommon: 6% to 17% of hospital sciatica clinics' patients meet the broader deep gluteal criteria. A slipped disc is the commonest cause of sciatica.
The piriformis wasn't thicker in people with the syndrome, one case improved with strengthening alone, and stretching alone did worse than combined programmes.
No trial supports it, and holds of several minutes sitting on the sore buttock can aggravate it: pain on sitting is a core feature.

Across 25 trials, stretching showed no protective effect, while strength training cut sports injuries to under a third; in 1,538 army recruits, stretching before exercise didn't reduce injuries. Stretch because it feels good, and build strength for protection.
Hypermobile people had higher odds of knee injury in contact sport, and one piriformis case pointed to overstretching rather than tightness. Range you can control matters more than range alone.
It can be a way to stay active and build hip strength, which is what the evidence points to, but no trial has tested yoga for it. Choose standing poses and bridges for strength, and keep stretches gentle and only if they ease the pain.
No trial shows it does. It may feel good for a stiff hip, but the front knee takes twisting load, and other positions stretched the piriformis more in a lab study. The reclined figure four is gentler; stop either if it sends pain down your leg.
At first, long seated poses on the sore buttock (lotus, cow face, long seated folds and long yin holds), forced pigeon or fire log, and folds over straight legs if your leg is symptomatic. Sitting is a common aggravator, and one severe case followed a sudden start to yoga and Pilates classes.
Poses that strengthen the hips: bridge, chair pose, warrior II and tree pose at a wall, then warrior III and half moon at a wall, which worked the buttock muscles hardest in a lab study. Add a reclined figure four if it eases the pain.
You often can't tell on your own. Pain below the knee with numbness or weakness, or pain that began with back pain, points to the back; deep buttock pain that is worse sitting points to the buttock. A lower back scan doesn't show the deep buttock, so get assessed if symptoms persist.
Rarely, it seems. One case report describes severe piriformis syndrome after three yoga and Pilates sessions in a woman who had been inactive for a year. Build up slowly, and don't force deep hip positions.
It hasn't been tested. Long holds sitting on the sore buttock can aggravate it, so keep holds short, sit on a block, or use lying versions such as the reclined figure four.
Neither has been tested. Both can build hip strength and gentle movement, so choose the one you enjoy. Our Pilates for piriformis syndrome guide covers Pilates.
If you do, keep it moving and off the middle of the buttock: a case report describes a sciatic nerve injury after ball self-massage there. Stop if it brings on leg symptoms.
No study gives a typical course with exercise; in the small trials, most people improved over 6 weeks to 4 months. If it isn't improving after a few weeks, or the pain spreads below the knee, get assessed.
Call 999 for sciatica in both legs, numbness around your genitals or bottom, new bladder or bowel trouble, or sudden breathlessness or chest pain. Get an urgent GP appointment or call NHS 111 for a swollen, painful calf, or a hot, swollen hip with a high temperature.
Exercise education, not a personal prescription, and clinical review of these guides is pending. If you are pregnant, have a health condition such as glaucoma, high blood pressure or osteoporosis, or have had recent surgery, check with a doctor, midwife or physiotherapist before starting, and stop for sharp or increasing pain.
