Sciatica
Pain that travels from the lower back down the leg — assessed, treated, and explained.
Sciatica treatment at Meridian Osteopathy in Christchurch addresses pain that travels from the lower back, through the buttock, and down the leg. We combine hands-on osteopathy — joint articulation, soft tissue release, and neural mobilisation — with acupuncture where it helps, plus targeted exercises between sessions. ACC-registered for injury-related sciatica; no referral needed. Sciatica is pain that travels along the sciatic nerve — from the lower back, through the buttock, and down the back of the leg to the ankle. It can range from a dull ache to a sharp, burning pain, and often comes with pins-and-needles, numbness, or weakness in the leg. Some people feel it mainly when they sit; others when they stand up after rest, roll over in bed, or cough and sneeze. The good news: most cases respond well to hands-on treatment, acupuncture, movement advice, and time. This page will help you understand what sciatica is, what is likely causing it, what the current evidence-based approach looks like, and when you should seek urgent medical attention.
Common signs of sciatica
- Sharp, burning, or electric pain that travels from the lower back through the buttock and down the leg
- Pins-and-needles, numbness, or tingling along the back of the leg, calf, or into the foot
- Pain that worsens when sitting, driving, or standing up after a period of rest
- A pulling or aching feeling along the back of the thigh that intensifies when you bend forward
- Weakness in the leg or foot — difficulty pushing off, walking on toes, or lifting the foot clear
- Symptoms that flare with coughing, sneezing, or straining, then ease with walking or lying flat
- Pain that follows a clear stripe down one leg rather than wrapping around the whole limb
When to see an osteopath for sciatica
- Sciatic pain has lasted longer than a week or is making sitting, driving, and sleep difficult
- The pain started after a specific lift, fall, or twist that you want assessed under ACC
- Symptoms are recurring or have flared multiple times in the past year
- Pregnancy, prolonged desk work, or a recent change in training is loading the lower back differently
- You have ongoing pins-and-needles or mild weakness but no red-flag symptoms (see below)
- Painkillers and rest alone are not shifting the pattern within the first 7–10 days
- You want a clear diagnosis, a plan, and exercises that will not flare the nerve further
What to expect at your first appointment
- A detailed history of the pain — onset, pattern, what helps, what flares it, and any leg symptoms
- A neurological screen — reflexes, sensation, and strength in the legs and feet to check the nerve root
- Movement testing of the lumbar spine, hips, and sacroiliac joints to find what is loading the nerve
- A plain-language explanation of what is likely irritating the sciatic nerve and a realistic timeline for recovery
- Hands-on treatment — joint articulation, soft tissue release around the gluteals, and neural mobilisation
- Two to three exercises — nerve gliders and positional strategies — to use between sessions without flaring symptoms
- An ACC claim lodged in clinic if a specific accident triggered the episode, plus a clear review plan
Common questions about sciatica
Sciatica is pain that radiates along the sciatic nerve — the body's longest nerve, running from the lower back through the buttock and down the leg. The pain can feel sharp, burning, or like an electric shock, and is often accompanied by numbness, tingling, or weakness. Importantly, sciatica is a symptom with many possible causes, not a single condition on its own.
The most common causes are a disc bulge or herniation in the lower back pressing on a nerve root, narrowing of the spinal canal (stenosis), arthritic changes in the lumbar facet joints, and piriformis syndrome — where the piriformis muscle in the buttock irritates the nerve. Pregnancy, prolonged sitting, heavy lifting, and sudden twisting movements can all trigger an episode.
Osteopathic treatment aims to reduce the load on the irritated nerve and restore normal movement through the lower back, pelvis, and hip. Techniques include gentle joint articulation, soft tissue release around the lumbar spine and gluteal muscles, and neural mobilisation ('nerve gliding'). Your osteopath will also give you specific exercises and posture advice to support recovery between sessions.
Yes — acupuncture can be a useful addition to hands-on osteopathy for sciatica, particularly when muscle spasm or chronic nerve irritation is part of the picture. We use a combination of Western medical acupuncture and traditional Chinese meridian points to release tight gluteal and piriformis muscles, settle inflammation around the irritated nerve, and calm the body's central pain response. The combined osteopathy + acupuncture approach often shortens recovery, especially for sciatica that has lingered beyond 4–6 weeks. Nina is dual-trained in osteopathy and medical acupuncture and can integrate both into the same session — useful when standalone manual therapy isn't quite enough.
Yes, if your sciatica is related to an accident or specific injury event. Our osteopaths are ACC-registered providers and can lodge a claim for you at your first visit — you don't need a referral. If there is no accident trigger (for example, sciatica from pregnancy, prolonged sitting, or gradual onset), treatment is paid privately at the non-ACC rate.
Most acute sciatica responds within 2–4 sessions over 2–4 weeks. Longer-standing sciatica, or cases involving disc changes, may need 4–6 sessions with gradual progression. Your osteopath will reassess at each visit and adjust the plan — if you are not responding as expected, they will refer you on for imaging or specialist review.
Many milder episodes of sciatica do settle within 4–6 weeks with relative rest, movement, and simple pain relief. However, early assessment and treatment usually shortens recovery, reduces the risk of recurrence, and helps you stay active — which is now the standard of care for back pain. Complete bed rest is rarely the right answer.
Seek urgent medical care (emergency department or GP) if you develop any 'red flag' symptoms: loss of bladder or bowel control, numbness around the groin or inner thighs, rapidly progressing leg weakness, or sciatica after a significant fall or trauma. These can signal a serious condition (cauda equina syndrome) that needs immediate specialist attention.
How we treat sciatica
At Meridian Osteopathy we treat sciatica with a combination of hands-on osteopathic techniques — gentle joint articulation, soft tissue release around the lumbar spine and gluteal muscles, and mobility work — alongside targeted exercises you can do between sessions. Where it helps, your practitioner can integrate Western medical acupuncture (dry needling) into the same session — particularly useful for stubborn gluteal or piriformis muscle spasm and for calming an irritated nerve. Our osteopaths are ACC-registered, so if your sciatica started with an injury, treatment is subsidised. You don't need a referral.
