Yoga for sciatica

Yoga for sciatica has modest evidence behind it, and the honest complication is that sciatica is not one thing. The word describes a symptom, pain running from the buttock down the back of the leg along the sciatic nerve, and the pain can come from at least two quite different places. What helps depends on which, and almost no page on this query says so.

The common cause by a long way is the spine. A systematic review published in BMC Surgery in 2025 reports that about 85 per cent of sciatica is associated with intervertebral disc disease, meaning a disc bulge or extrusion pressing on or irritating a nerve root as it leaves the lower back. The uncommon cause is the piriformis muscle deep in the buttock irritating the nerve as it passes, and the same review puts piriformis syndrome at somewhere between 0.3 and 6 per cent of low back pain and sciatica cases. So if you have sciatica, the odds are heavily that it is a disc and not a muscle, whatever a stretching video told you.

For the disc kind, there is direct evidence and it is encouraging. A randomised trial in Spine in 2022 put 48 patients with neuropathic pain from lumbar disc herniation into either patient education alone or education plus a stretch and strength based yoga programme, one hour twice a week for twelve weeks. The yoga group did significantly better on neuropathic pain, low back pain, disability and function, with between group effect sizes still moderate at six months. An earlier randomised trial in the Journal of Back and Musculoskeletal Rehabilitation took 61 rural adults aged 20 to 45 with disc extrusions or bulges, 62 per cent of them with sciatica, and found the yoga group scored 3.29 points better on the Roland Morris disability questionnaire at three months, with no adverse effects reported, and no significant difference on any other endpoint including pain and the straight leg raise. That last clause is the part usually left out.

For piriformis syndrome there is essentially nothing. No trial of yoga, and the treatment literature is dominated by injections and surgery rather than by exercise. Anybody telling you that a particular stretch treats piriformis syndrome is extrapolating.

And the timing. NICE guideline NG59 on low back pain and sciatica recommends group exercise programmes, including mind and body approaches, and advice to stay active, while explicitly not recommending traction, acupuncture or several electrotherapies. It also treats acute severe sciatica as a different situation, where the question is pain control rather than a class. In a genuine flare, rest, walking short distances and getting the pain under control beat practising, and I would rather say that than sell you a session.

It may support you alongside proper medical care. It does not put a disc back.

This is the half every incumbent page is thin on. In a flare, deep forward bending is the single most reliable way to make sciatica worse, and it is also the family of poses most students reach for, because the hamstring feels tight and stretching a tight thing seems obvious.

Here is why it is wrong. A disc bulge that is pressing on a nerve root sits at the back of the disc. Bending forward under load squeezes the front of the disc and pushes its contents backwards, towards the nerve. On top of that, a straight leg forward bend is mechanically a straight leg raise, which is the test doctors use to provoke sciatic nerve pain on purpose. So you are loading the disc towards the nerve and tensioning the nerve at the same time. The tightness you feel down the back of the leg in sciatica is frequently the nerve being pulled, not a short hamstring, and stretching a pulled nerve harder does not lengthen it.

• Paschimottanasana, the seated forward bend. Straight legs, loaded lumbar flexion, sitting, which is already the position that provokes sciatica most. Out entirely in a flare, and back later with bent knees, a folded blanket under the seat and a strap.
• Uttanasana, the standing forward fold. The same flexion, with gravity added and often with a bounce at the bottom. In a flare, if you must fold, bend the knees deeply and rest the hands on the thighs.
• Janu Sirsasana. A one legged forward bend, so all of the above lands on the side that hurts, plus a rotation.
• Halasana, plough. The deepest loaded flexion in the system with body weight through the neck. If there is any disc history in your spine, this is a firm no rather than a caution.
• Sirsasana and shoulderstand. Not taught to beginners here, and the exits are uncontrolled spinal movements under load, which is the last thing an irritated nerve root wants.
• Aggressive piriformis and hamstring stretching, held long. Not on the avoid list as a pose, but worth saying. Pulling hard on a nerve that is already irritated produces a flare a day later, reliably enough that I now teach hip work as short and gentle rather than as a stretch.

One important exception, and it is the reason this page keeps insisting on the cause. If your leg pain is worse standing and walking and better sitting, that pattern points away from a disc and towards spinal stenosis, and in stenosis the emphasis reverses: gentle flexion is often comfortable and extension is not. That is precisely why this needs a doctor's assessment before you pick poses from any page, mine included.

The whole page in one table. In a flare, do the first two and nothing else. Out of a flare, add one a week.

Everything in the avoid column except the last two comes back once the leg is quiet. The order matters more than the list: extension and hip strength first, forward bending last.

Split this by phase, because the mistake people make with sciatica is doing the right practice at the wrong time.

In an acute flare, the first week or two. Two things: makarasana or lying flat with a rolled towel under the knees, for as long as it is comfortable, and short walks. That is the whole practice. Guidelines agree on staying active and on getting the pain controlled, and they do not agree on any posture. This is the part of the page that is deliberately not selling you a class. Rest positions and a doctor beat a session, and pushing through is how a two week problem becomes a three month one.

Once the leg pain has stopped travelling further down, usually week two to four.

• Bhujangasana, low, forearms down, three breaths, three times. The rule is absolute: if the leg pain moves further down the leg, come out and do not repeat it. Pain that retreats towards the back is a good sign, pain that spreads towards the foot is not.
• Setu bandhasana, lifted a hand's width, five times. Hip strength, so the lower back stops compensating.
• Supta matsyendrasana, both sides, knees supported. The deep buttock ache is often the worst part at night and this addresses it without tension on the nerve.
• Gomukhasana legs only, thirty seconds, gentle. This is the piriformis work, done small, and small is the point.
• Savasana, eight minutes, knees supported.
• Nadi shodhana, eight rounds, on a chair.

From about week six. Standing poses at moderate depth, and forward bending reintroduced last, with bent knees and a long back, in that order and not the other way round. Most of the people who tell me yoga made their sciatica worse had reversed exactly this order. The back pain page is the natural next one, because once the leg is quiet what is left is usually a lower back that needs the same slow work.

Most sciatica settles over weeks with time, movement and pain relief. A small proportion is a serious problem and the first item on this list is a same day emergency.

• Any change in bladder or bowel control, difficulty passing urine, or numbness around the saddle area, the inner thighs or the genitals. This can be cauda equina compression and it needs a hospital today, not an appointment next week. Do not wait to see if it settles.
• Weakness in the leg or foot, particularly a foot that drags or slaps when you walk, or an inability to lift the front of the foot.
• Pain in both legs, or numbness in both legs.
• Leg pain that is worse standing and walking and better sitting or leaning forward, which points towards stenosis and reverses much of the advice on this page.
• Fever, unexplained weight loss, or a history of cancer, particularly with pain that is worse at night or at rest.
• The pain began with a fall or an accident, or in someone with known osteoporosis.
• Severe pain that is not touched by ordinary painkillers, or pain that has not improved at all in six weeks.

None of that is a reason to give up on yoga permanently. It is a reason to know what you are treating first, and in the case of the first item, immediately.

Week one to two, in a flare: the useful sign is not less pain but pain that retreats. Sciatica that pulls back from the foot to the calf, or from the calf to the buttock, is improving even if the number has not changed. Pain that spreads further down is the signal to stop and get assessed.

Week two to four: the leg quiets and the back becomes the main complaint, which feels like a setback and is actually the normal order. Most people can start gentle extension work here.

Week six to twelve: this is where the trial evidence sits. The Spine trial ran twelve weeks and found significant gains in neuropathic pain, back pain, disability and function, with moderate effects still present at six months. The disc extrusion trial found a three point gain on a disability score at three months and nothing significant on the other measures. Expect function and confidence to move more than the pain score does.

Beyond three months: most disc related sciatica has settled by now with or without a practice, and the practice earns its place in what happens next, which is not having it again. That is a matter of hip strength, standing up from a desk, and never going back to hauling on a straight leg forward bend.

One line a day. The first item is the one to take seriously, because it is the number that tells you whether to continue or to stop.

1. How far down the leg the pain reaches, in words: buttock, thigh, calf, foot. This is more useful than a pain score. Retreating up the leg is improvement. Spreading down it means stop practising and get assessed, whatever the pain score says.
2. Sitting tolerance in minutes, before you have to stand up. Sitting is the position that provokes disc related sciatica most, so this is the functional measure that changes first and the one your work actually depends on.
3. Which of the two rules you broke, if any: a forward bend with straight legs, or a long held stretch of the painful leg. Nine times out of ten a bad week has one of those in it, and writing it down is how you find out.

Bring these to class. A student who says the pain has come up from the calf to the buttock and can now sit for twenty minutes instead of five gets a different session from one who says it still hurts.

The reason to have a teacher for sciatica is that the two decisions that matter are judgement calls, not instructions. The first is when to start, and the honest answer in a flare is not yet. The second is how to read the leg during a pose: pain retreating is permission to continue, pain spreading is a reason to come out immediately, and a student practising alone at home almost always misreads that, because both of them feel like the pose is doing something. Watching somebody's face in a low cobra tells you more than asking them does.

The classes here are traditional yoga taught slowly by one teacher across about forty years, at a residents' association hall, to students of all ages. If you have been searching for yoga for sciatica near you, the in person classes run in north Bangalore, in the hall at MSR Nagar, with students from Mathikere, Malleswaram and Yeshwanthpur. If sitting in an autorickshaw is currently the worst part of your day, the live online classes are the sensible option, and you can stand up and walk about in the middle of one without disrupting anybody. The first class is free. Come and say how far down the leg it goes, and if the answer is that it is spreading, I will tell you to see a doctor first.
