Sciatica is not a disease but a symptom: pain radiating from the lower back or buttock down the back or outside of the thigh, often on into the calf and foot, sometimes with tingling, numbness or weakness. The cause is irritation of the sciatic nerve or one of the nerve roots that form it, most often by a disc herniation or a narrowing in the lower spine, sometimes by a tight buttock muscle ("false sciatica"). Most people recover on their own within six to twelve weeks with movement, pain relief and patience. Here is what helps, which warning signs need medical care now, and how cupping can be used for the muscles around the problem, but not on the nerve.
What is sciatica?
The sciatic nerve is the thickest nerve in the body. It is formed by nerve roots from the lower spine and sacrum, passes under or through the buttock muscles and runs down the back of the leg. When a nerve root is compressed or irritated, for example by a disc bulging against it, pain arises along the nerve's whole distribution, hence the radiation down the leg. Typically the leg pain is worse than the back pain, coughing, sneezing and bending forward hurt, and it is usually one-sided. Disc herniation is most common between 30 and 50; in older people it is more often an age-related narrowing of the spinal canal (spinal stenosis), which gives aching legs when walking and eases when bending forward or sitting down.
False sciatica (piriformis syndrome) means that a deep buttock muscle, the piriformis, is so tight that it presses on the nerve where it passes. The pain then sits mostly in the buttock and back of the thigh, and is worse after sitting for long on a hard surface. This is where self-care and cupping are most useful. If only the lower back hurts, without radiation, it is more likely lumbago or ordinary lower back pain.
When to see a doctor
Call emergency services or go to A&E if you get numbness in the groin or around the back passage, difficulty passing urine or controlling your bladder or bowels, or rapidly increasing weakness in the leg or foot (you trip, cannot stand on your toes or heel). These can be signs that the nerves are seriously compressed and need assessment straight away. See a doctor the same day if the pain came after a fall or accident, if you have a fever, if you have or have had cancer, or if you are losing weight without trying. Contact your doctor if numbness or weakness is increasing, if the pain is so severe that you cannot sleep or manage daily life despite pain relief, or if you are not better after six weeks.
Self-care that helps
- Move, as much as you tolerate. Walks on flat ground, ideally several short ones a day. The nerve does best when the body is moving. Avoid heavy lifting and deep forward bends in the first weeks.
- Sit less and change position often. Sitting increases pressure in the discs. Stand, walk and lie down instead. When you must sit, sit high with support in the small of the back.
- Find your offloading position. Many get relief lying on their back with the legs on a chair (the "90–90 position") or on their side with a pillow between the knees. With spinal stenosis, bending forward usually eases it.
- Pain relief as advised by your pharmacist or doctor, so that you can stay active. Nerve pain sometimes responds less well to ordinary painkillers; talk to your doctor if it is not enough.
- Heat on the lower back and buttock eases the muscle tension that almost always comes with it.
- Nerve gliding exercises and gentle mobility, ideally shown by a physiotherapist: seated knee extensions, pelvic tilts, cat–cow. Do not stretch hard on the radiating leg; it can irritate the nerve more.
- Patience and gradual return. Nerves heal slowly. Expect weeks, and increase activity a little at a time.
Cupping for sciatica: what works and what to avoid
Cupping cannot affect a disc herniation or a narrowing. What it can do is help the muscles that tense up around the problem to let go: the gluteal muscles, the piriformis and the long lower back muscles. In false sciatica these muscles are often the whole explanation, and then cupping can make a big difference. The ground rule: cup the muscles, not the nerve. Do not cup along the back of the leg where it radiates, and not where you have reduced sensation. You need someone to help you, the dynamic cup, static cups and body oil.
- Warm up the lower back and buttock with a shower or heat pad for ten minutes.
- Lower back, light suction. Slow strokes upwards along the back muscles a hand's width from the spine, five strokes per side. Never on the spine itself.
- The buttock. Oil the whole buttock. Glide the cup in circles and in strokes from the sacrum out towards the hip. The piriformis sits deep here; work patiently with light to moderate suction, not hard.
- Static cups on the most tender points in the gluteal muscle, one to three at a time, two to three minutes. If you feel radiation, tingling or numbness under a cup, remove it immediately and move to another point.
- The outside of the thigh can be cupped lightly if the muscles are tight, but skip the back of the thigh when it radiates there.
- Finish with heat, gentle movement and a short walk.
Twice a week is about right while the problem lasts. How static and dynamic cupping work in principle is in Cupping at home, and the whole back is covered in Cupping on the back. If you sit a lot, the guide for people who sit a lot is a good follow-on once the worst is over.
When not to cup
Not if you have any of the warning signs above, not where you have numbness or reduced sensation, not along the nerve's path when it radiates, not over the spine, not on wounds, rashes or bruises, and not without medical advice if you are pregnant, take blood thinners, have osteoporosis or cancer in your history. If cupping increases the radiation, stop and discuss it with your physiotherapist.
Frequently asked questions
How long does sciatica last?
Most people are clearly better within six to twelve weeks, even with a disc herniation, because the herniation shrinks on its own. Some feel it for longer, and with spinal stenosis the symptoms are often more drawn out and come and go.
Does cupping help with sciatica?
Not the nerve compression itself, but the tight muscles in the buttock and lower back that come with it and that, in false sciatica, are the actual cause. Cup the muscles, not the nerve, and never where it is numb.
Should I stretch with sciatica?
Gentle mobility for the lower back and buttock is good. Hard stretching of the back of the radiating leg can irritate the nerve more; be careful and let a physiotherapist show you nerve gliding exercises instead.
Can I exercise with sciatica?
Yes, in adapted form: walking, cycling, swimming and light strength training without heavy lifts or deep forward bends. Activity that does not increase the leg pain the next day is generally fine.
What is the difference between sciatica and lumbago?
Lumbago hurts in the lower back, sometimes towards the buttock, but not down the leg. Sciatica radiates below the knee and can give tingling, numbness or weakness. They can occur together.
