Sciatica

Sciatica isn’t a diagnosis in itself but a description of pain that travels along the sciatic nerve — the long nerve running from the lower back, through the buttock, and down each leg. It usually happens when the nerve is compressed or irritated, most often by a herniated disc, but also by spinal narrowing (stenosis) or a tight piriformis muscle. Because the pain follows the nerve’s path, it can extend well below the knee, and the underlying cause affects how it’s best managed.

Sciatica has a recognizable set of features:

• Pain radiating from the lower back or buttock down the back of the leg
• Sharp, burning, or electric-shock quality, often on one side
• Numbness, tingling, or ‘pins and needles’ along the nerve’s path
• Pain that worsens with sitting, coughing, or certain movements
• Sometimes weakness in the affected leg or foot

The most common cause is a herniated disc pressing on a nerve root; other causes include spinal stenosis, degenerative changes, and piriformis muscle tightness. Because certain symptoms — progressive weakness or changes in bladder or bowel control — can signal a medical emergency, a physician’s evaluation is considered important, especially for new, severe, or worsening sciatica.

In Chinese medicine, sciatica is often approached through the Bladder and Gallbladder channels, which run down the back and along the side of the leg, following the very path sciatic pain tends to take. The pain is typically understood as Qi and Blood stagnation obstructing these channels — sometimes with Cold or Damp contributing, sometimes against a background of Kidney deficiency in longer-standing cases. Treatment aims to relieve stagnation, free the channels, and restore smooth flow down the leg, easing both pain and tension around it.

Acupuncture is used for sciatica to target the tight muscles and irritated nerve pathway of the lower back, buttock, and leg, aiming to ease pain and support the body’s natural pain-modulating response. Points are often selected locally along the affected channel and at distal sites, and electrical stimulation is frequently added for nerve-related pain.

For the tight muscle bands — especially in the buttock and piriformis — that can pinch or aggravate the nerve, dry needling is often used to release those areas directly.

Sciatica is one of the more encouraging areas of acupuncture research. A 2024 randomized clinical trial published in JAMA Internal Medicine found that, for chronic sciatica from a herniated disc, real acupuncture led to less leg pain and better function than sham acupuncture at four weeks — with benefits that persisted through a full year (Tu et al., JAMA Internal Medicine, 2024). A sham-controlled result in a major medical journal is meaningful, though the study focused specifically on disc-related sciatica. Acupuncture is offered here as a supportive complement to a patient’s care, matched to the individual.

A first visit begins with a conversation about how the pain started, where it travels, what makes it worse, and whether there’s any leg weakness or numbness — plus what medical care and imaging have already taken place. Dr. Willcox will assess the lower back, hip, and leg before selecting a point protocol that may combine local and distal points, electroacupuncture, and dry needling of the buttock muscles. Because nerve pain can take time to settle, relief often builds over a series of sessions, and treatment pairs well with appropriate movement and stretching.
