Sciatica

Sciatica is the sharp, radiating leg pain that happens when the sciatic nerve gets pinched somewhere along its path. The pain can travel from the low back all the way down to the foot, and it can make sitting, standing, and sleeping miserable.

Overview

Sciatica is a symptom, not a diagnosis. The pinch on the nerve almost always starts in the low back, often from a herniated disc, spinal stenosis, or an arthritic joint pressing on a nerve root.

Most patients improve with targeted, image-guided injections that reduce the inflammation around the nerve. Surgery is rarely the first step.

Symptoms & causes

Sciatica has a classic pattern. Recognizing it is the first step toward relief.

Sharp, shooting, or burning pain down one leg
Pain that gets worse with sitting, sneezing, or bending forward
Numbness, tingling, or weakness in the leg or foot
Low back or buttock pain that feeds the leg pain

When to see a doctor

Seek care if…

Seek care urgently for new bladder or bowel changes, loss of sensation in the saddle area, or progressive leg weakness. These can signal a serious nerve compression that needs same-day evaluation.

Frequently asked questions

How long should I wait before seeing a specialist?

If leg pain is severe, if it lasts more than a few weeks, or if you have new weakness or numbness, it is time for a specialist. Waiting months usually makes treatment harder, not easier.

Will I need surgery?

Most patients with sciatica improve without surgery. A well-timed injection and a short course of physical therapy resolve the majority of cases. Surgery stays reserved for red flags or cases that fail conservative care.

How quickly does an epidural work?

Many patients feel better within a few days to a couple of weeks. The benefit can last months, and if it wears off, a second injection often extends the relief.
