Sciatica

Understanding Sciatica

The sciatic nerve is the largest nerve in the body, running from the lower spine through the buttock and down the back of the leg to the foot. When it is compressed or irritated anywhere along that route, the brain often feels the result further down the leg than the actual problem — which is why sciatica is felt in the leg even though the source usually sits in the lower back or buttock. The good news is that the large majority of sciatica settles with conservative care and does not need surgery or injections, though it typically takes a little longer to resolve than ordinary back pain because irritated nerves calm down slowly.

Common Signs & Symptoms

• Pain running from the lower back or buttock down the back of one leg
• Numbness, tingling, or pins and needles in the leg or foot
• A burning or electric-shock quality to the pain
• Pain made worse by sitting, coughing, or sneezing
• Weakness in the leg or foot in more pronounced cases
• Pain that is often worse in the leg than in the back itself

Common Causes of Sciatica

Lumbar disc bulge or herniation

The most common cause — a disc in the lower back presses on or chemically irritates a nerve root as it exits the spine. Most disc-related sciatica improves steadily with conservative care over a matter of weeks.

Piriformis and deep buttock tension

The sciatic nerve passes close to the piriformis muscle deep in the buttock. When that muscle is tight or overloaded it can irritate the nerve, producing sciatica-type pain without a disc being involved.

Spinal stenosis

A narrowing of the space around the nerves in the lower spine, more common with age. It tends to give leg pain that builds when walking or standing and eases when you sit or lean forward.

Lumbar joint restriction

Stiff or irritated joints in the lower back can contribute to nerve irritation and to the muscle guarding that keeps sciatica going.

Pregnancy-related sciatica

The postural and pelvic changes of pregnancy can load the lower back and irritate the nerve. Treatment is gently adapted to your stage of pregnancy.

How Osteopathy Helps with Sciatica

The first step is working out what is irritating the nerve — a disc bulge, tight buttock muscles, spinal narrowing, or joint restriction in the lower spine each need a different emphasis. Treatment usually combines soft-tissue work through the buttock and hip, gentle articulation of the lumbar spine, and graded nerve-mobilising movements that help the nerve glide more freely. We also advise on sitting positions and activity so you avoid the things that keep the nerve aggravated. Because sciatica can be slow to settle, a good deal of the value is in guiding you through it — knowing what is normal, what helps, and what to avoid.

Techniques we may use

• Soft-tissue work through the buttock, hip, and lower back
• Gentle articulation to restore movement to the lumbar spine
• Neural mobilisation ("nerve flossing") to help the nerve glide freely
• Muscle energy technique to ease deep buttock and hip tension
• Graded exercise and positional advice to keep the nerve settling
• Manipulation where appropriate and with your consent

What You Can Do Yourself

Avoid long periods of sitting where you can — it is usually the most aggravating position. Short, frequent walks tend to help. Positions that ease the leg pain (often lying on your back with knees bent, or with a pillow under the knees) are worth using for rest breaks. Keep gently moving within comfort; recovery is usually gradual rather than overnight, and doing a little often beats long spells of complete rest.

Sciatica: Your Questions Answered

Is sciatica the same as back pain?

No. Sciatica is nerve pain felt mainly in the leg, though the cause usually sits in the lower back or buttock. You can have back pain without sciatica, sciatica without much back pain, or both together — the assessment works out which applies to you.

How long does sciatica take to improve?

Most cases settle over weeks rather than days — typically longer than simple back pain, because irritated nerves calm down slowly. Treatment aims to speed that process and stop the problem recurring. We will give you a realistic timescale after assessing you.

Can osteopathy help sciatica, and how?

Yes — for the great majority of sciatica, which is caused by nerve irritation from a disc, tight muscles, or a stiff lower back rather than by anything needing surgery. We ease the muscle guarding, restore movement to the lower back and hip, help the nerve glide more freely, and guide your activity so the nerve keeps settling.

Should I keep working and moving with sciatica?

Within comfort, yes. Staying gently active generally helps sciatica recover, whereas long spells of complete rest tend to prolong it. We will help you adapt sitting, driving, and work so you can keep moving without repeatedly flaring the nerve.

Do I need a scan or surgery for sciatica?

Usually neither. The large majority of sciatica improves with conservative care and time. Scans are reserved for cases that are not settling as expected or that show warning signs, and surgery is considered only for a small minority. We will tell you honestly if we think you need onward referral.

What is the difference between sciatica and a trapped nerve?

They overlap. "Trapped nerve" is an everyday term for a nerve being compressed or irritated; sciatica is that happening specifically to the sciatic nerve or the roots that form it, giving pain down the leg. The assessment identifies where the nerve is being irritated and why.

When is sciatica an emergency?

Go straight to A&E if you develop numbness around the saddle area, changes to bladder or bowel control, or worsening weakness in both legs. These can indicate cauda equina syndrome, which needs immediate hospital assessment. We screen for these signs at every appointment.
