Sciatica Treatment: Causes, Symptoms & 5 Physiotherapy Exercises for Leg Pain

Sciatica is one of the most uncomfortable pains people describe to us — a burning, electric or shooting pain that starts in the lower back or buttock and travels down the back of the leg, sometimes all the way to the foot. Effective sciatica treatment starts with understanding what is irritating the nerve, then calming it down with the right movement, positions and exercises. Most people recover without surgery.

What is sciatica?

The sciatic nerve is the longest nerve in the body. It is formed by nerve roots that leave the lower spine, join together in the buttock and run down the back of each leg. “Sciatica” is the name for pain, tingling or numbness along this nerve. It is a symptom, not a diagnosis — something is irritating or compressing the nerve.

Common causes of sciatica

• Disc bulge or herniation – the most common cause. The soft centre of a lumbar disc pushes outwards and irritates a nerve root. (See our article on slip disc treatment without surgery.)
• Spinal stenosis – narrowing of the spaces around the nerves, usually in people over 50, often worse when walking.
• Spondylolisthesis – one vertebra slipping forward on another.
• Piriformis and deep buttock tightness – sometimes contributes to buttock and leg pain.
• Pregnancy – changes in posture and load can irritate the nerve.

Risk factors include heavy lifting with twisting, long hours of sitting or driving, being overweight, smoking and low physical activity.

Symptoms of sciatica

• Pain that travels from the buttock down the back or side of the leg, often below the knee
• Burning, shooting or “electric current” sensations
• Pins and needles or numbness in the leg or foot
• Pain that worsens with sitting, coughing, sneezing or bending forward
• Usually affects one leg only
• In some cases, weakness in the foot or ankle

Red flags: when sciatica is an emergency

Seek emergency medical help immediately if you have:

• Numbness around the genitals or buttocks (saddle area)
• Difficulty passing urine, or loss of bladder or bowel control
• Sciatica in both legs at the same time
• Rapidly increasing weakness, such as foot drop or legs giving way

These can be signs of cauda equina syndrome, which needs urgent surgical assessment.

How long does sciatica last?

Many people with sciatica from a disc problem improve significantly within 4 to 6 weeks, and continue to improve over the following months. Nerve symptoms such as tingling often take longer to settle than pain. If symptoms are severe, getting worse, or not improving after 6 weeks of good conservative care, your physiotherapist will refer you for a medical review and, if needed, imaging.

How physiotherapy treats sciatica

Finding the cause

A physiotherapy assessment checks spinal movement, posture, which positions ease or increase leg pain, and nerve function (sensation, reflexes and muscle strength). This helps separate disc-related sciatica from stenosis, joint problems or muscle-related buttock pain — each is treated differently.

Calming the irritated nerve

In the early phase, the aim is to reduce pressure on the nerve. This may include finding relief positions, directional exercises (for many disc problems, gentle backward-bending helps the leg pain move back towards the spine), manual therapy, and electrotherapy such as TENS for pain relief.

Nerve mobility and core strength

Once pain settles, nerve-gliding exercises restore normal nerve movement, and core, hip and leg strengthening prepares you to return to work, sport and lifting.

Daily habit changes

Sitting posture, sleeping positions, two-wheeler riding, lifting technique and work breaks are adjusted so the nerve is not repeatedly irritated.

5 gentle exercises for sciatica

Do these slowly and stop any exercise that makes leg pain spread further down the leg. A good sign is when pain moves up towards the back (called centralisation).

1. Prone lying – Lie on your tummy for 2–3 minutes, breathing slowly. If comfortable, progress to the next exercise.
2. Prone press-up (McKenzie extension) – Lying on your tummy, place hands under shoulders and gently push your upper body up while keeping hips on the floor. Lower slowly. 10 repetitions. Only continue if leg pain does not worsen.
3. Sciatic nerve glide – Sit tall on a chair. Straighten your affected knee while lifting your head to look up, then bend the knee as you look down. Move smoothly 10 times; this should not be painful.
4. Knee-to-chest stretch – Lie on your back and gently draw one knee towards your chest for 20 seconds. Useful especially for stenosis-type pain that eases when bending forward.
5. Walking – Short, frequent walks on level ground keep the spine moving and reduce stiffness. Start with 5–10 minutes several times a day.

Avoid during a flare-up: long periods of sitting, heavy lifting, deep forward-bending stretches like touching your toes, and sudden twisting.

Sitting and sleeping with sciatica

• Sit with a small cushion or rolled towel behind your lower back, feet flat, and get up every 20–30 minutes.
• Sleep on your side with a pillow between your knees, or on your back with a pillow under your knees.
• When getting out of bed, roll to your side first and push up with your arms.

Do I need surgery for sciatica?

Most people do not. Surgery is usually considered only when there are emergency signs, significant or worsening weakness, or severe pain that has not improved after a good period of conservative treatment. Even after surgery, physiotherapy is important to restore strength and movement.
