Understanding the evidence. Getting the right treatment.
Tracking your progress.
From your first acute flare to full return to activity, the complete Atherapy sciatica resource
Many people arrive worried they have permanently damaged their spine. Others fear they will need surgery. Most are surprised, and relieved, to learn how often sciatica resolves with the right approach. For many patients, understanding what is happening reduces fear almost immediately.
If you have sciatica, you will know it. The pain does not stay in your back: it travels. Down through your buttock, into your thigh, sometimes all the way to your foot. It can burn, shoot, ache, or go numb. It can wake you at night.
Usually, something manageable is happening: a disc in your lower spine is pressing on a nerve. That sounds alarming, but the evidence is genuinely reassuring: disc herniations reduce in size on their own in the majority of cases, and most people recover significantly with the right treatment.
⚠️ URGENT, When to Go to A&E
If you have any changes to your bladder or bowel, numbness in the saddle area (inner thighs or groin), or rapidly worsening weakness in both legs: go to A&E immediately or call 999. Do not wait for a physiotherapy or GP appointment.

At a Glance
Most people with sciatica improve without surgery. At an initial assessment, Atherapy clinicians focus on:
- Identifying which nerve root is affected and how severely
- Ruling out any symptoms that need urgent medical attention
- Determining your directional preference, the movement pattern that settles the nerve
- Building a movement-based recovery programme around that finding
- Tracking progress objectively at every appointment
Quick Answer
Key findings, each referenced in full below.
- Sciatica is nerve pain, not back pain. It travels from the lumbar spine down the leg via the sciatic nerve, typically caused by a disc pressing on a nerve root.
- Most herniations resolve without surgery. 90% show measurable reduction in size over time (Chiu et al., AJNR, 2015).
- Bed rest slows recovery. Graded activity consistently produces better outcomes than rest (Hagen et al., Cochrane, 2010).
- Direction-specific physiotherapy outperforms generic exercise. Treatment built around how your nerve responds at assessment produces significantly better outcomes (Browder et al., JOSPT, 2007).
- Surgery and conservative management reach equivalent outcomes at one to two years. Early surgery offers faster short-term relief but equal long-term results (Peul et al., NEJM, 2007).
What Is Sciatica?
Sciatica is pain that travels along the sciatic nerve (the largest nerve in the body, running from the lower spine through the buttock and down each leg to the foot. The term describes a symptom, not a diagnosis: it tells you where the pain is going, not what is causing it.
In the majority of cases, the cause is a lumbar disc herniation. The discs between the vertebrae act as cushions. When the outer layer weakens, the inner material can press outward; if it presses on a nerve root, the result is pain that travels down that nerve's path into the leg.
The character of the pain is typically different from back pain. It may burn, shoot, or feel like an electric shock. It may be accompanied by numbness, tingling, or weakness in the leg or foot. Other causes include spinal stenosis, spondylolisthesis, and (less commonly) piriformis syndrome, where a gluteal muscle irritates the nerve directly.

What the Evidence Says
The research on sciatica is more reassuring than most patients expect. Five findings in particular shape how Atherapy's senior physiotherapy team approaches every case.
Disc herniations reduce in size on their own
Chiu CC et al., American Journal of Neuroradiology, 2015. This systematic review found that 90% of lumbar disc herniations showed measurable reduction in size without surgical intervention. The largest herniations showed the greatest tendency to reduce. This is the evidence base for honest reassurance at initial assessment: the disc pressing on the nerve commonly reduces in size over time.
What the clinician says
The question I am most often asked is: 'Will this get better?' The honest answer, and the evidence-based answer, is yes, in most cases. What varies is how quickly, and how completely, depending on how it is managed.
Andrew Balderston MSc, HCPC, MCSP, AACP
Direction-specific treatment outperforms generic exercise
Browder DA et al., Journal of Orthopaedic and Sports Physical Therapy, 2007. This randomised controlled trial compared direction-specific exercise with generalised strengthening in patients with lumbar radiculopathy (nerve pain radiating down the leg). The direction-specific group showed significantly greater improvement. Treatment at Atherapy is built around this principle: the programme follows the nerve, not a standard protocol.
Surgical and conservative outcomes converge at one to two years
Peul WC et al., New England Journal of Medicine, 2007. This landmark trial compared early disc surgery with conservative management in patients with severe sciatica. Outcomes were equivalent at one year. Early surgery produced faster short-term relief, but the difference resolved. For most patients, surgery is an option, not an inevitability, and the decision should be made on clinical grounds rather than anxiety.
Bed rest is not beneficial
Hagen KB et al., Cochrane Database of Systematic Reviews, 2010. Bed rest is no more effective than staying active, and may produce worse outcomes. The instinct to rest when in pain is understandable. The evidence does not support it.
NICE recommends physiotherapy as first-line treatment
NICE Guideline NG59, 2016 (updated 2020). Exercise and physiotherapy are recommended as first-line management for sciatica. Routine early imaging is not recommended. Scanning is appropriate where findings would change management, typically when surgical opinion is being considered or red flag features are present.
What Often Makes Sciatica Worse
Several common responses to sciatica, most of them instinctive, consistently slow recovery or worsen symptoms. Understanding them is part of clinical management.
Sustained sitting increases intradiscal pressure. Most patients find leg pain worsens after 20–30 minutes seated. Frequent short walks and position changes help significantly.
Repeatedly checking 'how bad is it today', bending forward, pressing on sore areas, keeps the nervous system activated. It prevents the natural downregulation that supports recovery.
Avoiding movement weakens spinal support structures and can sensitise the nervous system. It can also create fear-avoidance (a pattern where movement becomes feared independently of the original injury, sustaining pain beyond the disc itself).
A good day is not a signal to catch up on everything avoided. This pattern reliably produces a significant flare the following day. Recovery is not linear.
Forward bending and hamstring stretches are among the most common self-treatments, and among the most likely to aggravate in the acute phase. Whether stretching helps or harms depends on the individual clinical picture.
Exercise prescribed without knowing how the nerve is behaving can worsen symptoms. This is the most common reason self-directed physiotherapy from the internet fails to help, and sometimes makes things worse.
What Recovery Usually Feels Like
Recovery from sciatica has a characteristic pattern. Knowing what to expect can significantly reduce the anxiety that often accompanies it.
- Burning becomes aching. The sharp, shooting quality of acute nerve pain typically softens to a duller ache as the nerve settles. This is a positive sign.
- Pain centralises. Leg pain moving upward (from the foot or calf toward the buttock), is called centralisation. It is the most reliable indicator of a good response to treatment.
- Good days and bad days are normal. Recovery is rarely linear. Increased symptoms following activity do not indicate a setback: they are a normal feature of nerve recovery.
- Tingling may outlast pain. Neurological symptoms, numbness, tingling in the foot, can persist for weeks after pain has resolved. Nerve tissue recovers more slowly than soft tissue. This is not a sign of ongoing damage in most cases.
- Morning stiffness is common. Discomfort on waking is typical in disc-related sciatica. It usually eases within 20–30 minutes of movement.
What the clinician says
The single most reassuring sign in clinic is centralisation: when a patient says the pain has moved from the foot to the buttock. That shift tells me the nerve is settling and the approach is working. Most patients don't know to look for it. I explain it at the first appointment.

How Long Does Sciatica Last?
The timeline below is evidence-informed and realistic, not aspirational. Individual recovery varies with the severity of symptoms, the presence of neurological findings, and how promptly a focused treatment approach is established.
The Atherapy Approach
Atherapy's approach to sciatica is shaped by 20 years of clinical practice in elite football, Nottingham Forest and Hull City FC, applied to every patient, regardless of their level of activity. The same criteria-based framework used at Premier League level informs how a first appointment with an office worker in acute pain is structured.
The distinction is not a technique or a piece of equipment. It is the rigour of the assessment, the precision of the treatment decision, and the objectivity of how progress is tracked.
What Recovery Can Look Like
The narrative below is anonymised clinical experience, not a testimonial or a guarantee. It illustrates a typical presentation and the clinical process that follows.
A typical patient presentation - based on anonymised clinical experience
Office worker, 35, with 8-week left-sided sciatica
A 35-year-old in financial services presented with eight weeks of progressive left-sided leg pain. He had rested completely for two weeks on a colleague's advice, with no improvement. Assessment identified an L5 nerve root pattern with a clear directional preference: extension reduced leg pain; flexion increased it. PSFS: 3/10. A direction-specific programme was prescribed alongside postural guidance. Leg pain resolved over eight sessions. Residual foot tingling cleared four weeks later. Return to running at week ten. PSFS at discharge: 8/10. No surgical intervention.
Assessment and Referral
Every sciatica patient begins with a full clinical assessment, not a triage appointment. The aim is a complete clinical picture and an honest conversation about prognosis and the most appropriate pathway.
What the assessment covers
- A detailed history: symptom onset, behaviour, what aggravates and what relieves, and what has already been tried.
- Full neurological examination, dermatomal sensation, myotomal strength, and deep tendon reflexes, to establish a baseline and identify any deficit requiring medical referral.
- Assessment of lumbar movement and directional preference: how the spine and nerve respond to specific movements. This is the finding that shapes the treatment programme.
- Screening for red flag features and cauda equina symptoms.
- PSFS and NPRS administered at baseline, then repeated at four weeks and discharge, objective tracking, not clinical impression.
When physiotherapy is the right pathway
Most patients with acute or subacute sciatica respond well to structured physiotherapy. NICE NG59 supports conservative management as first-line treatment, and the evidence favours a movement-based approach over rest or generic exercise.When onward referral is appropriate
When onward referral is appropriate
Not every sciatica presentation is a physiotherapy case. Onward referral is recommended where:
- Red flag features are present, cauda equina symptoms require immediate A&E, not a physiotherapy appointment.
- Progressive neurological deficit is identified: worsening weakness or increasing neurological change not responding to conservative management. Surgical decompression is indicated where deficit is progressive (Jacobs et al., European Spine Journal, 2011).
- Symptoms have not responded adequately, following a complete course of physiotherapy, typically eight to twelve weeks.
- Surgical opinion is being considered, Atherapy has established referral pathways to Fortius, BUPA, HCA, and Schoen Clinic, and can coordinate this directly.
When surgery is considered
Surgery is not the default outcome for sciatica, but it is the right pathway for some patients. Atherapy clinicians will raise it when:
- Progressive neurological deficit. Worsening foot drop or leg weakness that is not responding to conservative management. Surgical decompression may be indicated on clinical grounds independent of pain levels.
- Cauda equina symptoms. Changes to bladder or bowel, saddle numbness, or bilateral leg weakness require immediate A&E: surgical decompression is a medical emergency in this context.
- No meaningful improvement after structured physiotherapy. Typically defined as insufficient progress after eight to twelve weeks of a well-executed, direction-specific programme.
- Severe, persistent radicular pain. Where quality of life is significantly impaired and conservative management has been fully explored, surgical consultation is a reasonable next step.

When to seek urgent help
Go to A&E immediately or call 999 if you have:
- Changes to your bladder or bowel
- Numbness in the saddle area (inner thighs or groin)
- Rapidly worsening weakness in both legs
If you are unsure, call NHS 111. If symptoms are severe or rapidly worsening, call 999 or go to A&E.
Full guidance: /sciatica/red-flags/
When should I go to A&E?
Go to A&E immediately — or call 999 — if you have:
- Difficulty passing urine or unexpected bladder leakage
- Loss of bowel control or inability to sense when you need the toilet
- Numbness in the saddle area (inner thighs, perineum, genitals)
- Rapidly worsening weakness in both legs
Call NHS 111 if uncertain. Do not wait overnight.
Is surgery inevitable with sciatica?
No — for the large majority, it is not. Peul et al. (NEJM, 2007) found that surgery and conservative management produce equivalent outcomes at one year: early surgery relieves pain faster, but the difference resolves. Surgery becomes the appropriate pathway for progressive neurological deficit not responding to treatment, cauda equina symptoms (a surgical emergency), or insufficient progress after eight to twelve weeks of well-executed physiotherapy. Most patients do not reach that point.

Ready to Take the Next Step?
A sciatica assessment begins with a complete clinical picture: neurological examination, movement assessment, and an honest conversation about what the evidence says about your specific presentation and your options.
Most people with sciatica improve significantly. Understanding what is happening with your nerve, and having a clear plan built around that finding, is usually the turning point.
Testimonial
Patient Experience with ACL Rehabilitation
Truly invaluable
"Claire at Atherapy has been truly invaluable. After rupturing my ACL, I was understandably cautious and unsure about the best path forward to get back to playing football, particularly given the long timeframe of recovery. From the outset, she has combined deep expertise with genuine care and patience. She took the time to explain each stage of the recovery process, tailored the rehab to my goals, and consistently provided reassurance and encouragement. Her knowledge, empathy and attention to detail have given me real confidence that I am progressing safely and effectively. I'm incredibly grateful for the support she's provided throughout, and I would not hesitate to recommend her to anyone going through a similar injury or looking for high-quality physiotherapy."
ACL Reconstruction –
4 Weeks Post-Op
“I couldn’t be happier with the care and support provided throughout my recovery. The Game Ready made a real difference in managing swelling and comfort early on, and I feel ahead of where I expected to be at this stage.”
Using Game Ready in the first few weeks after my ACL reconstruction made a noticeable difference in managing swelling and keeping the knee comfortable
“It helped me stay consistent with my early rehab exercises, particularly in that first month when the knee is most reactive. It became part of my daily routine alongside physio, rather than a standalone treatment.”
The Game Ready ice machine has made a real difference to my recovery speed.
"I couldn’t be happier with the care and support Andrew has provided throughout my ACL reconstruction recovery. He’s calm, patient, considerate, and always available to answer any questions you may have. His approach combines expert guidance with professional tools, like the Game Ready ice machine, which has made a real difference to my recovery speed. At just a month post-op, I’m already well ahead of where I’d expect to be at this stage. If you’re looking for a physio to guide you through injury recovery, Andrew is your guy. You’ll be treated with the same level of attention and professionalism as a Premier League footballer, and my recovery is a testament to that."
