6 Sciatica Stretches and Exercises That May Help Relieve Your Pain

If you have sciatica, you already know the pain. That deep ache in the buttock, the shooting sensation down the back of your leg, the numbness or tingling that makes it hard to get comfortable — it is not something you can just ignore.

The good news is that movement is usually your friend when it comes to sciatica. The right stretches and exercises can help reduce pressure on the sciatic nerve, ease muscle tension, and restore some of the mobility that pain takes away. The key word there is right — not every exercise is helpful for every type of sciatica, which is why a proper assessment matters.

That said, these six movements are among the most commonly recommended for sciatic nerve pain, and most people find at least some of them helpful. Try them gently, and stop anything that significantly increases your pain or causes symptoms to travel further down the leg.

A quick note before you start

Sciatica is a symptom, not a diagnosis. It means something is irritating your sciatic nerve — and that something could be a disc bulge, joint restriction, tight piriformis muscle, or something else entirely. The exercises below are general in nature. If your pain is severe, getting worse, or accompanied by weakness or bowel and bladder changes, see a healthcare provider before attempting these. If you have not had your sciatica properly assessed, it is worth doing so — the right approach depends on the cause.

1. Piriformis stretch (figure-four)

The piriformis muscle sits deep in the buttock, right next to the sciatic nerve. When it is tight or in spasm, it can compress the nerve and cause or worsen sciatica symptoms. This stretch targets it directly.

How to do it: Lie on your back with both knees bent and feet flat on the floor. Cross your right ankle over your left knee, creating a figure-four shape. Gently draw your left knee toward your chest until you feel a stretch in the right buttock. Hold for 30 seconds, then switch sides. Repeat 2–3 times each side.

What you should feel: A stretch deep in the buttock of the crossed leg. Not pain shooting down the leg.

2. Knee-to-chest stretch

This gentle sciatica stretch helps decompress the lower lumbar spine and relieve some of the pressure that may be aggravating the sciatic nerve.

How to do it: Lie on your back with both knees bent. Gently draw one knee toward your chest with both hands and hold for 20–30 seconds. Lower and repeat on the other side. You can also draw both knees to your chest at the same time for a more general lower back release.

Tip: This is often a good first movement in the morning before getting out of bed.

3. Supine spinal rotation

A gentle rotational stretch for the lower back that can help ease stiffness and reduce nerve tension without loading the spine.

How to do it: Lie on your back with your knees bent. Keeping your shoulders flat on the floor, gently let both knees fall to one side. Hold for 20–30 seconds, breathing slowly. Bring your knees back to centre and repeat on the other side.

Go gently: If rotating toward one side significantly increases your pain, avoid that direction and stick to the more comfortable side for now.

4. Cat-cow

A classic movement that mobilises the entire spine, encourages fluid movement through the lumbar discs, and gently activates the deep core muscles. It is one of the best exercises for sciatica because it is low-load and can be modified easily.

How to do it: Start on all fours with your hands under your shoulders and knees under your hips. Breathe in, let your belly drop toward the floor, and lift your head and tailbone (cow). Breathe out, tuck your chin and tailbone, and round your back toward the ceiling (cat). Move slowly and rhythmically for 10–15 repetitions.

5. Bird-dog

This exercise builds stability in the deep core and lower back without compression — making it one of the more useful exercises for sciatica relief when the pain has started to ease a little.

How to do it: On all fours, brace your core gently, then slowly extend your right arm and left leg until both are roughly parallel with the floor. Hold for 3–5 seconds, then return and repeat on the other side. Aim for 8–10 repetitions on each side. Keep your back flat — avoid letting your hips rotate or your lower back arch.

6. Sciatic nerve floss

Nerve flossing (or neural mobilisation) is a technique that gently moves the sciatic nerve through its surrounding tissues, which can reduce neural tension and sensitivity. It should feel like a stretch — not sharp pain.

How to do it: Sit upright on a chair. Straighten one knee so your leg is extended in front of you, then gently flex your foot (toes toward you). Hold for 3–5 seconds, then relax the knee back down. Repeat on the other side. Do 10–15 repetitions each side, moving slowly and smoothly. If you notice a significant increase in symptoms down the leg, ease off the range and try again more gently.

Exercises and positions to avoid with sciatica

Just as some movements help, others can aggravate sciatic nerve pain — at least in the acute phase. Common ones to be cautious with include:

• Sitting for prolonged periods without getting up
• Heavy deadlifts or bent-over rows
• Full sit-ups or double leg raises
• Any movement that causes sharp pain to shoot into the leg

This is not forever — once the nerve settles and you have addressed the underlying cause, most exercises can be reintroduced gradually. But in the acute stage, less is more.

How long will these exercises take to work?

There is no universal answer — it depends on how long you have had sciatica and what is causing it. Some people notice improvement within a few sessions of consistent gentle exercise. Others find that exercises alone are not enough, and that the underlying cause (a restricted joint, a disc bulge, tight piriformis) needs hands-on attention before the exercises become effective.

If you have been doing sciatica stretches and exercises for a couple of weeks without improvement, that is a good signal to get a proper assessment rather than just adding more exercises to your routine.

When to see a chiropractor for sciatica

A chiropractic assessment for sciatica will identify what is actually irritating your sciatic nerve — and from there, we can recommend the specific movements and approaches most likely to help your situation. This might include spinal adjustments to restore joint mobility, targeted soft tissue work on the piriformis or surrounding hip muscles, personalised exercise guidance, and advice on managing your symptoms day-to-day.

If your sciatica is affecting your sleep, your work, or your ability to get around comfortably — do not just keep stretching and hoping for the best. Come and see us at Banora Chiropractic in Tweed Heads South. We will work out what is going on and help you get on top of it.
