Sciatica Treatment with Physiotherapy: 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.
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.
