Sciatica Physio: Treatment with Physiotherapy and What Helps
Sciatica is one of the most common problems we treat at Bluebell — and one of the most rewarding, because most people respond well to structured physiotherapy without needing injections or surgery. This page explains what sciatica actually is, how we treat it, and what to expect.
What is Sciatica?
Sciatica is the term used for pain caused by irritation or compression of the sciatic nerve (or the nerve roots that feed it in the lower back). It's a symptom rather than a diagnosis — the underlying cause is usually a disc, a joint or tight muscle putting pressure on the nerve as it exits the spine.
Typical Symptoms
- Sharp, burning or shooting pain from the lower back or buttock down the back of the leg
- Pins-and-needles, numbness or a heavy feeling in the leg, calf or foot
- Pain worse when sitting, driving, sneezing or bending forward
- Weakness in the leg — for example, difficulty pushing off when walking
- Symptoms typically on one side (both sides is less common and needs urgent review)
Common Causes & Triggers
- Lumbar disc bulge or herniation pressing on a nerve root (most common)
- Degenerative changes narrowing the space where the nerve exits the spine (foraminal stenosis)
- Piriformis syndrome — the piriformis muscle in the buttock compressing the nerve
- Facet joint irritation referring pain down the leg
- Poor movement patterns loading the lumbar spine (long-hours driving, prolonged sitting, heavy manual work)
How We Treat Sciatica at Bluebell
- 1
A proper subjective and physical assessment — not a 10-minute box-tick. We map the exact nerve pattern and rule out red flags.
- 2
Hands-on treatment to reduce pain: soft-tissue work on the buttock/hip muscles, spinal mobilisation, and neural mobilisation (nerve gliding).
- 3
Specific rehab: directional preference exercises (McKenzie method where indicated), core control and hip/glute strength work.
- 4
Electrotherapies where appropriate — TECAR, laser or ultrasound can reduce pain-sensitivity and speed early recovery.
- 5
Return-to-activity plan: driving, sitting tolerance, lifting technique and progressive loading so it doesn't come back.
Honest Recovery Timeline
Most people with straightforward sciatica start feeling meaningful change within 2–4 weeks (3–6 sessions). More stubborn cases — long history, previous flare-ups, or a significant disc issue — usually take 8–12 weeks of consistent work. We reassess at every visit so you know whether you're on track.
Sciatica, trapped nerves and what physio looks for
Many people describe sciatica as a trapped nerve in the back. More precisely, a nerve root in the lower back is irritated, often by a disc, and the pain travels along the path of the sciatic nerve into the buttock and leg. A sciatica physio assessment checks how far symptoms travel, how the back moves and whether strength, reflexes and sensation in the leg have changed. That helps decide what treatment fits and whether you need medical review as well. Our disc bulge page explains disc-related causes.
Which specialists treat sciatica?
Physiotherapists, GPs and, for a small number of people, spinal specialists all play a part. A GP can discuss pain relief, check for other causes and refer you on if needed. Physiotherapy focuses on movement, exercise and advice to help you manage day to day. A referral to a spinal surgeon or pain specialist is usually only considered when symptoms are severe, getting worse or not improving after a reasonable period of treatment. There is no single best sciatica treatment for everyone, and be wary of anyone promising a quick cure.
What A&E will and will not do
A&E is for emergencies. If you have numbness around the genitals or buttocks, new bladder or bowel problems, or weakness in both legs, go straight away, because these need urgent investigation. For severe sciatica without those signs, A&E staff may check for serious causes and offer pain relief, then advise follow-up with your GP or physiotherapy. If you are unsure where to go, NHS 111 can help you decide.
What to wear and bring
Wear loose clothing such as shorts or tracksuit bottoms so your back and legs can be assessed comfortably. Bring a list of medicines, any scan or hospital letters and notes on which positions make the pain better or worse. We are at Warren Road, Blue Bell Hill, Chatham ME5 9RD, with free parking, and you can book directly without a GP referral. If you are coming from the West Malling side, our sciatica page for West Malling patients covers arranging care from there.
When Sciatica Needs Urgent Medical Attention (Not Physio)
- •Loss of bladder or bowel control, or numbness in the saddle or groin area, go to A and E immediately.
- •Sudden severe weakness in a leg or foot (foot drop), same day GP or A and E.
- •Unexplained weight loss, night sweats or fever with the back pain, see your GP.
- •Back pain or leg symptoms after significant trauma such as a fall from height or a road traffic collision, urgent medical review before any physiotherapy.
Sciatica — Common Questions
How long does sciatica take to get better with physio?
For most people 2–6 weeks of consistent physiotherapy produces meaningful change. Around 80% of straightforward sciatica settles within 8–12 weeks with the right treatment and self-management, without needing injections or surgery.
Should I rest or keep moving with sciatica?
Keep moving within tolerance. Prolonged bed-rest actually delays recovery. We'll show you which positions and exercises ease your symptoms and which to avoid short-term.
Do I need an MRI before starting physio?
No — for most cases imaging is not needed to start treatment. If your presentation doesn't improve as expected, or if we spot anything unusual, we'll refer you for imaging or specialist review.
Can shockwave or TECAR help sciatica?
TECAR and low-level laser can reduce pain sensitivity and help you tolerate exercise sooner. Shockwave is more useful for tendon issues than nerve pain — we'll pick the right tool for your presentation.
What if my sciatica keeps coming back?
Recurrence usually means the underlying driver (posture, hip weakness, disc load pattern) hasn't been addressed. We build a maintenance plan around your work and lifestyle so flare-ups become less frequent and much shorter.
Can you help if I've already had a lumbar injection or surgery?
Yes — post-injection and post-surgical rehab is a big part of our work. We coordinate with your consultant's plan and take you from initial recovery back to full activity.
What is the first treatment for sciatica?
For most people it is staying as active as comfort allows, simple pain relief if suitable, and an assessment to guide exercise and positions that ease the leg pain. Seek urgent help straight away for numbness around the bottom or genitals or any change in bladder or bowel control.
Which specialists treat sciatica?
Physiotherapists and GPs manage most sciatica. Spinal specialists are involved when symptoms are severe, worsening or not settling with treatment.
Which doctor treats sciatica nerve pain?
Start with your GP for medical advice and pain relief. They can refer you to a spinal or pain specialist if needed, and you can also see a physiotherapist directly.
What's the best way to cure sciatica?
There is no single cure. Staying active within comfort, guided exercise and time help most people, and an assessment shows what suits your symptoms.
What will A&E do for sciatica pain?
They check for emergency signs such as bladder or bowel changes and leg weakness, may offer pain relief and advise follow-up with your GP or physiotherapy.
Is emergency sciatica treatment ever needed?
Yes, if you have numbness around the genitals or buttocks, new bladder or bowel problems or weakness in both legs. Go to A&E immediately.
