Sciatica often begins with a twinge in the lower back that unexpectedly travels down the leg, turning everyday movements into a challenge. This nerve-related discomfort affects countless individuals, disrupting sleep, work and simple pleasures like a leisurely walk.
Put simply, sciatica is your body’s signal that the sciatic nerve is under stress. This nerve is the longest in the human body, stretching from the lower spine through the hips and into the legs.
Recognising Sciatica Symptoms
The symptoms can vary, but they typically include:
- Sharp, shooting pain radiating from the back to the thigh or calf
- Sensations like an electric jolt or persistent burn
- Tingling or numbness, similar to pins and needles
- Muscle weakness that makes lifting your foot feel unsteady
These sensations often worsen with prolonged sitting, bending forward or even coughing, highlighting how everyday actions can amplify the irritation.
What makes sciatica particularly frustrating is that it is not a standalone condition. Rather, it is a symptom pointing to an underlying issue in the spine or surrounding tissues. Recognising these signs early allows for timely intervention, which can prevent the pain from becoming a chronic companion.
Common Causes of Sciatic Nerve Irritation
At its core, sciatica stems from pressure or inflammation along the sciatic nerve pathway, often due to changes in the spine or muscles.
Herniated Discs
A herniated disc occurs when the soft centre of a spinal disc pushes through its outer layer, pressing on nearby nerve roots. This is the leading culprit, affecting around 90% of cases according to clinical studies. Such an event might follow a sudden lift or twist, leading to that familiar leg pain that does not match the back discomfort.
Degenerative Changes
Degenerative disc disease, where age-related wear narrows the spaces around nerves, gradually builds irritation over time. Facet joint dysfunction or spinal stenosis, common in older adults, can also play a role by inflaming joints or constricting the spinal canal.
Piriformis Syndrome
The piriformis syndrome adds another layer. This small muscle in the buttocks can tighten and squeeze the nerve, especially in those who sit for hours or play sports like golf that demand hip rotation.
Lifestyle Factors
Prolonged sitting without breaks weakens core stability, while sudden overuse from activities like padel or gym sessions can tip the balance if flexibility lags behind strength. These elements often combine, making personalised assessment crucial for targeting the true source.
Proven Approaches to Easing Sciatica
When it comes to sciatica treatment, the most reliable paths forward involve restoring movement and reducing pressure on the nerve through targeted, hands-on care.
Chiropractic Adjustments
Chiropractic adjustments can help to improve restrictions in joints and ease pressure on the discs that compress local nerves. Along with local muscle work, joint mobilisations and home exercises in certain cases can give significant relief.
Physiotherapy
Physiotherapy can help by tackling the biomechanical imbalances at play. Through exercises focused on core strengthening, hip mobility and neural gliding, therapists guide you towards lasting stability. Over a few weeks, this can transform how your body handles daily loads, cutting down on future flare-ups. Our physiotherapists at Costa health often combine manual therapy and exercises to help settle disc injury’s.
Spinal Decompression
Spinal decompression techniques offer another gentle option, particularly for disc-related issues, by creating space in the spine to promote healing and rehydration. These are techniques used by our Chiropractors and Physiotherapists.
Soft Tissue Work
Soft tissue work, like myofascial release or massage, targets tight glutes, hamstrings and the piriformis to release built-up tension that exacerbates nerve sensitivity.
Building Long-Term Strength
Building strength forms the cornerstone of long-term management. Focusing on glutes, deep abdominals and lower back stabilisers prevents recurrence, as weak muscles fail to shield the spine adequately. Research shows that structured rehabilitation reduces symptoms by up to 70% in the first six months.
Approaches That Fall Short
Not every common suggestion holds up under scrutiny, and some can even prolong discomfort.
Extended Bed Rest
Bed rest might seem intuitive after the initial onset, but staying immobile beyond a day or two weakens muscles that support the spine, potentially worsening inflammation and stiffness. Movement, in moderation, actually aids recovery by promoting circulation and gentle nerve mobilisation.
Over-Reliance on Painkillers
Over-relying on painkillers masks the issue without resolving the mechanical root, leading many to cycle through episodes without progress.
Aggressive Stretching
Aggressive stretching, particularly of the hamstrings, can tug on the nerve if done incorrectly, heightening irritation rather than soothing it.
Quick Tip: Avoid generic online exercise programmes for sciatica. They often overlook individual variations and may incorporate movements that inadvertently compress the spine further. A personalised assessment ensures exercises match your specific condition.
When to Seek Professional Care
Knowing the right moment to seek help can spare you unnecessary suffering. Consider consulting a specialist if:
- Pain persists beyond a week
- Numbness and tingling spread down the leg
- You have difficulty walking, sleeping or bearing weight on the affected side
- You notice weakness affecting foot control
- Symptoms developed after lifting something heavy
- You experience recurrent back or leg discomfort
Early intervention not only accelerates healing but also safeguards against complications like chronic pain.
Red Flag Symptoms Requiring Urgent Attention
Seek immediate medical evaluation if you experience:
- Loss of bladder or bowel control
- Numbness around the groin or saddle area
- Rapidly worsening leg weakness
- Severe, unrelenting pain after trauma
These may indicate serious nerve involvement requiring urgent care.

Frequently Asked Questions
What exactly is sciatica?
Sciatica is a set of symptoms caused by irritation or compression of the sciatic nerve or its nerve roots. It typically creates pain, tingling, numbness or weakness that travels from the lower back into the buttock and down the leg.
What does sciatica pain feel like?
Many people describe it as a sharp, shooting pain or an electric shock-like sensation down the leg. Others feel a deep burning ache, numbness, pins and needles, or heaviness in the limb.
Can sciatica occur without back pain?
Yes. Some people feel very little lower back discomfort but have strong leg symptoms. Sciatica is often more noticeable in the leg than in the back.
What is the most common cause of sciatica?
A herniated or bulging disc is the most common cause. This happens when disc material presses on nearby nerve roots, triggering radiating leg pain and other symptoms.
Is sciatica a diagnosis or a symptom?
It is a symptom, not a diagnosis. Sciatica indicates there is an underlying issue such as disc irritation, spinal joint dysfunction, stenosis, or muscle-related compression like piriformis syndrome.
How long does sciatica usually last?
It varies. Mild cases can improve within days to a few weeks. More persistent or severe nerve compression can take longer and may need structured care. Early treatment often shortens recovery time.
Is walking good for sciatica?
In many cases, yes. Gentle walking improves circulation, keeps the spine moving and reduces stiffness. The key is staying within tolerable pain levels and avoiding long periods of sitting.
Should I rest in bed with sciatica?
Only briefly if the pain is intense. Extended bed rest usually slows recovery by weakening supportive muscles and increasing stiffness. Controlled movement is generally better than prolonged inactivity.
What activities make sciatica worse?
Common triggers include prolonged sitting, bending forward repeatedly, twisting under load, heavy lifting, and sometimes coughing or sneezing due to pressure changes in the spine.
Are stretching exercises always helpful?
Not always. Aggressive hamstring stretching can sometimes worsen nerve irritation because the sciatic nerve runs through the same region. Targeted nerve glides and mobility work are often safer early on.
What are nerve glides and do they work?
Nerve glides are gentle movements designed to help the sciatic nerve move freely without sticking or being irritated. When done correctly, they can reduce tension and improve symptoms over time.
Can chiropractic care help sciatica?
It can, especially when symptoms are linked to spinal joint restriction, disc-related irritation or poor mechanics. Adjustments aim to reduce pressure on sensitive structures and restore healthier movement.
How does physiotherapy help with sciatica?
Physiotherapy addresses the underlying biomechanics with core strengthening, hip mobility work, posture correction and progressive loading. It helps prevent recurrence, not just symptom relief.
What is spinal decompression and who is it for?
Spinal decompression techniques aim to create space between spinal segments, which may reduce disc pressure and support healing. It is often used in disc-related cases where compression is a key factor.
Can medication cure sciatica?
Medication can reduce pain and inflammation temporarily, but it does not correct the mechanical cause. It is best used as part of a wider plan rather than the main solution.
When should I seek professional help for sciatica?
Seek care if symptoms last more than a week, worsen quickly, or include increasing numbness, tingling or weakness. Recurrent episodes are also a strong reason to get assessed.
What are red flag symptoms that need urgent medical attention?
Get urgent evaluation if you experience loss of bladder or bowel control, numbness around the groin or saddle area, rapidly worsening leg weakness, or severe unrelenting pain after trauma. These may indicate serious nerve involvement.
Can sciatica come back after it improves?
Yes, especially if the root cause is not addressed, such as a weak core, poor hip mobility, repetitive strain or prolonged sitting habits. Strengthening and movement strategies significantly reduce recurrence risk.
What can I do at home to relieve sciatica?
Helpful options include short frequent walks, gentle nerve glides, heat or ice depending on what feels better, avoiding prolonged sitting and heavy lifting, and maintaining neutral posture during daily tasks.
Do I need imaging (MRI) for sciatica?
Not always. Many cases improve without imaging. MRI is usually considered if symptoms are severe, persistent, worsening, or associated with neurological weakness, or if conservative care fails.
