Sciatica

What is Sciatica?

Sciatica is pain that travels from your lower back or buttock down the leg, following the path of the sciatic nerve. The pain can range from a dull ache to a sharp, burning sensation, and it often comes with tingling, numbness, or weakness in the affected leg.

Here’s the thing: sciatica isn’t a diagnosis in itself. It’s a symptom. It tells you that the sciatic nerve is irritated or compressed somewhere along its path, but it doesn’t tell you why. That’s what matters.

The good news: sciatica is very common and very treatable. Most people recover well with the right approach. You don’t need to live with it, and you probably don’t need surgery. What you need is an accurate diagnosis of what’s causing your nerve symptoms, and a structured plan to settle them.

Common Causes of Sciatica I Treat

Sciatica has different causes, and treatment depends on identifying which one you’re dealing with. Here’s what typically brings people through the door across Chester and the wider Cheshire area.

Disc-Related Sciatica

The classic. A disc herniation or bulge in your lower back compresses a nerve root, causing pain that radiates down the leg.

This is the most common cause of sciatica, particularly among gym-goers who’ve been deadlifting or squatting heavy, manual workers lifting awkwardly, or anyone who’s bent forward to pick something up and felt a sudden onset of back and leg pain.

Symptoms are usually worse with bending forward, sitting for long periods, coughing, or sneezing. Pain often travels down one leg, sometimes all the way to the foot. You might get numbness or tingling in specific areas depending on which nerve root is affected.

Here’s what most people don’t know: the majority of disc herniations resolve naturally over time. Your body reabsorbs the disc material that’s compressing the nerve. Surgery is rarely needed. What you need is a plan to manage symptoms while that happens and to prevent it happening again.

Piriformis Syndrome

The piriformis is a small muscle deep in your buttock. When it gets tight or irritated, it can compress the sciatic nerve that runs underneath or sometimes through it.

Common among runners, cyclists, and people who sit a lot — particularly desk workers across Chester and Cheshire who’ve spent years sitting with poor posture or with a wallet in their back pocket.

Symptoms: Deep buttock pain that travels down the leg, worse with sitting, driving, or running. Often confused with disc-related sciatica, but the pain pattern and triggers are different.

Responds well to targeted stretching, soft tissue work, and addressing the underlying movement patterns or strength deficits that caused it in the first place.

Lumbar Stenosis

Narrowing of the spinal canal, usually due to age-related changes in the spine. More common in older adults, but I see it occasionally in younger athletes who’ve had previous spinal injuries.

Symptoms: Leg pain and sometimes weakness that’s worse with walking or standing, and relieved by sitting or bending forward. This is the opposite of disc-related sciatica, where sitting makes it worse.

The pain often affects both legs rather than just one. People describe it as their legs feeling heavy or weak after walking a certain distance.

Surgery is sometimes needed for severe cases, but many people manage lumbar stenosis very well with physio — core stability work, postural strategies, and activity modification.

Nerve Root Irritation

Sometimes the nerve gets sensitised and inflamed without significant structural compression. There might be a small disc bulge, or inflammation around the nerve root, but nothing major on a scan.

This is often inflammatory in nature and settles well with time and the right management approach. The prognosis is usually excellent.

Symptoms can be similar to disc-related sciatica but tend to respond faster to treatment. Pain might be sharp and severe initially but improves significantly within 4-6 weeks with good management.

What You Can Expect in Your Assessment

I’ll take a detailed history — how the pain started, what makes it worse, what positions ease it, whether you’ve got any numbness, tingling, or weakness.

Then I’ll do a neurological screening: testing sensation, muscle strength, reflexes. I’ll perform nerve tension tests to see how sensitive the sciatic nerve is, and assess your spinal movement and core stability.

Often I’ll watch you move — bending, squatting, walking — to understand how your spine and hips are working together and where the problem might be coming from.

By the end of the session, you’ll have:

Do I Need a Scan?

Usually not immediately. Most sciatica can be diagnosed and treated without imaging.

Clinical examination is enough to identify whether you’ve got disc-related sciatica, piriformis syndrome, or nerve irritation. We can start treatment straight away without waiting for a scan.

You might need imaging if:

• Symptoms aren’t improving after 6-8 weeks of good conservative management
• There are significant neurological signs — progressive weakness, loss of reflexes, or concerning sensory changes
• There’s a possibility of something more serious that needs ruling out
• We’re considering a specialist referral and they’ll need imaging to make treatment decisions

Here’s the reality: an MRI might show a disc bulge, but disc bulges are found in loads of people with no pain at all. Research shows that over 50% of people in their 40s have disc bulges on MRI who’ve never had back pain or sciatica.

What matters isn’t whether you have a disc bulge on a scan. What matters is whether that disc bulge is the thing causing your symptoms, and whether it needs surgical intervention or will settle with conservative management. Clinical assessment tells us that.

If imaging is needed, I’ll guide you on the best route — NHS referral via your GP (free but slower), or private MRI if you want results quickly.

Why Rest Alone Doesn’t Work

People rest their back, avoid bending and lifting, stop going to the gym, and wait for the sciatica to settle. Pain improves a bit. They go back to normal activities and it flares up again within days. Sound familiar?

Here’s why that happens: rest reduces pain by removing the aggravating activities, but it doesn’t fix the underlying problem — usually poor spinal mobility, weak core stability, movement patterns that overload certain areas of the spine, or general deconditioning.

When you return to activity at the same level you were at before resting, you’re asking a deconditioned spine to handle loads it couldn’t manage when it was stronger. No surprise it breaks down again.

What Does Sciatica Rehab Involve?

Depends on the specific cause, but here’s what most sciatica rehab programmes include:

Pain management strategies: Identifying positions and movements that ease symptoms — often this involves avoiding prolonged sitting or forward bending initially. Some people respond well to gentle extension exercises, others to flexion-based movements. It’s individualised.

Nerve mobilisation: Once acute symptoms start settling, we introduce gentle nerve gliding and flossing exercises to reduce nerve sensitivity and improve mobility. This isn’t aggressive stretching — it’s controlled, progressive movement to desensitise the nerve.

Core and spinal stability: Building strength and control around the spine to support it better and reduce load on the discs and nerve roots. This is non-negotiable for preventing recurrence.

Movement reintroduction: Gradually reintroducing bending, lifting, and rotational movements with good technique. The goal is to rebuild confidence and capacity, not to avoid these movements forever.

Strength building: Addressing any weakness in the legs, glutes, or core that’s developed during the painful period. Sciatica often causes muscle inhibition and deconditioning — we need to reverse that.

Return to normal activities: Progressive return to gym training, running, manual work, or whatever activities you need to get back to. This is structured and based on symptom response, not guesswork.

How Long Does Recovery Take?

Realistic timescales for common causes of sciatica:

Acute disc-related sciatica: 6-12 weeks for most people. The first 2-4 weeks can be rough, but symptoms typically start improving after that as the disc settles and nerve irritation reduces. You won’t be completely out of action — we modify activities and keep you moving within tolerance.

Piriformis syndrome: 4-8 weeks with targeted treatment. Usually responds faster than disc-related sciatica once we’ve addressed the muscle tightness and underlying movement issues.

Lumbar stenosis management: Ongoing. This is about symptom management and maintaining function rather than “curing” the stenosis. Most people see significant improvement in symptoms within 8-12 weeks of starting a good rehab programme.

Nerve root irritation (inflammatory): 4-8 weeks. Often settles faster than disc herniations because there’s less structural compression. The nerve just needs time to calm down.

These are broad ranges. Your specific timeline depends on how severe the initial injury was, how long you’ve had symptoms before seeking treatment, and how well you engage with the rehab programme.

Some people feel significantly better within 2-3 weeks. Others take the full 12 weeks or longer. But the trajectory should be clear improvement over time, not static or worsening symptoms.

When to Book an Assessment

If you’re experiencing those red flag symptoms, don’t wait for a physio appointment. Get yourself to A&E. They’re rare, but they’re serious and need immediate medical intervention.

For everyone else: sciatica is treatable. You don’t need to put up with it, and you don’t need to wait months hoping it’ll go away on its own.
