Should I rest in bed for sciatica?

No. Prolonged bed rest actually delays recovery. Gentle movement and walking are recommended, along with specific directional exercises prescribed by a physical therapist.

Back Pain Radiating to Leg: Sciatica, Disc Issues, and More

Important Disclaimer

This guide is for informational purposes and does not replace professional medical advice. If you are experiencing a medical emergency, call 911 or your local emergency services immediately.

Overview

Pain radiating from the lower back into the leg typically follows the sciatic nerve pathway, indicating nerve root compression. The most common cause is a lumbar disc herniation pressing on the L4-S1 nerve roots.

Possible Causes

Sciatica (Disc Herniation)

common

A herniated lumbar disc compresses the sciatic nerve, causing pain radiating from the buttock down the back of the leg.

View Condition Details

Spinal Stenosis

less-common

Narrowing of the spinal canal compresses nerves, causing leg pain and weakness that worsens with walking.

Piriformis Syndrome

less-common

Tightness in the piriformis muscle in the buttock compresses the sciatic nerve, mimicking disc-related sciatica.

When It Is Serious

Progressive leg weakness, foot drop, numbness in the groin/saddle area, or loss of bowel/bladder control (cauda equina syndrome) require emergency evaluation.

When It's Likely Benign

Mild radiating pain that improves with position changes and responds to stretching/NSAIDs typically resolves in 4-6 weeks.
