That sharp, shooting pain travelling from your lower back down through your leg is one of the most recognisable symptoms in musculoskeletal care. If it sounds familiar, you are not alone.

Short answer: What is sciatica and how is it treated? Sciatica is compression or irritation of the sciatic nerve, causing pain, tingling, or weakness along the nerve's path. It is treated effectively with chiropractic care, physiotherapy, and targeted exercise -- without surgery in most cases.

Quick overview:

• Sciatica describes symptoms caused by sciatic nerve irritation, not a standalone diagnosis

• Pain typically runs from the lower back through the buttock and into one leg

• Most cases resolve with conservative care -- surgery is rarely needed

• Chiropractic and physiotherapy in Isleworth address both the nerve compression and the surrounding muscles

What Is Sciatica, Exactly?

Sciatica is a clinical term for symptoms caused by irritation or compression of the sciatic nerve -- the longest nerve in the body. It runs from the lower spine, through the hips and buttocks, and branches down each leg.

When something presses on or inflames this nerve, the signal becomes disrupted. The result is the characteristic radiating pain most people describe as a burning heat or electric shock. It almost always affects one side of the body.

What Are the Symptoms of Sciatica?

Because the sciatic nerve is so long, symptoms vary depending on where the irritation occurs. Common signs include:

• Radiating pain: a sharp, searing sensation travelling from the lower back down the back of the thigh and into the calf

• Numbness or tingling: "pins and needles" in the leg or foot

• Leg weakness: difficulty flexing the foot or pushing off when walking

• Posture-related pain: discomfort that worsens when coughing, sneezing, or sitting for extended periods

What Causes Sciatica?

Several spinal and muscular conditions can compress the sciatic nerve. Identifying the correct cause shapes the treatment approach.

Herniated or Slipped Disc

This is the most common cause. The soft discs between your vertebrae act as shock absorbers. When one bulges or herniates, it can press directly on the nerve root exiting the spine.

Spinal Stenosis

As we age, the channels through which nerves travel can narrow (stenosis). This narrowing creates pressure on the nerves as they exit the spinal column, particularly in the lower back.

Spondylolisthesis

This is when a vertebra slips forward over the one below it. The resulting misalignment can pinch the sciatic nerve and cause lower back nerve pain that radiates down the leg.

Piriformis Syndrome

Not all sciatic pain originates in the spine. The piriformis muscle sits deep in the buttock, directly over the sciatic nerve. When it tightens or spasms -- often from prolonged sitting -- it can compress the nerve without any disc involvement.

How Is Sciatica Treated With Chiropractic and Physiotherapy?

At Isleworth Pain and Injury Studio, we use a combined approach to address both the structural cause of the compression and the muscles around it.

Chiropractic Care

Chiropractic adjustments focus on restoring normal movement to the joints of the spine. By reducing mechanical stress at the point of nerve compression, adjustments can ease the "pinching" sensation and improve lower back mobility.

Physiotherapy

Physiotherapy targets the muscles that support and protect the spine. Specific exercises strengthen the core, improve flexibility, and reduce the strain on the irritated nerve. Soft tissue therapy also helps release tension in muscles such as the piriformis.

By combining both disciplines, we address the compression itself and build the muscular support system that keeps it from returning. You can read more about our approach on our sciatica treatment page, or book a consultation directly at isleworthpainandinjury.co.uk/contact.

Red Flags -- See a GP or Healthcare Professional If:

• You lose control of your bladder or bowel

• You experience sudden, severe weakness in both legs

• Pain follows a significant injury such as a fall or road accident

• You have unexplained weight loss alongside the nerve pain

• Symptoms do not improve or are getting progressively worse over several weeks

Frequently Asked Questions

How long does sciatica last?

Most acute episodes improve within 4 to 6 weeks with appropriate conservative care. Chronic cases may take longer but respond well to treatment.

Is sciatica the same as lower back pain?

No. Lower back pain stays local. Sciatica radiates from the back down through the buttock and leg, following the path of the sciatic nerve.

Can physiotherapy for sciatica make it worse?

A well-structured physiotherapy plan should not worsen sciatica. Some initial discomfort during assessment is normal. Always inform your therapist if pain increases.

Do I need an MRI scan before treatment?

Not always. Many cases are diagnosed through clinical assessment. Imaging is recommended if symptoms are severe, worsening, or not responding to initial treatment.

Can chiropractic care help sciatica caused by a slipped disc?

Yes. Chiropractic adjustments can reduce pressure on the affected nerve root and improve spinal mobility, even when a herniated disc is the cause.
