Lower Back Pain Radiating Down the Leg? Here's What It Means and What to Do
Updated July 20261 minute read
Pain that starts in your lower back and travels down your leg usually means a spinal nerve is irritated — most often from a herniated disc, a pattern known as sciatica. It can feel sharp, burning, or electric, sometimes with numbness or tingling. Most cases improve within weeks to a few months with movement and physical therapy. Groin numbness or loss of bladder/bowel control is an emergency — seek care immediately.
What this usually means
Most likely causes. Radiating leg pain points to nerve irritation. A herniated disc pressing on a nerve root is the leading cause (sciatica). In older adults, spinal stenosis can produce leg symptoms with walking. Less common causes. SI joint or deep hip/buttock muscle issues can refer pain into the leg, though usually not as far or as "electric."
What you can try at home
Find positions that ease the leg pain (for many people, gentle movement and avoiding prolonged sitting help) and keep walking within comfort. Avoid bed rest. Because leg symptoms involve a nerve, a guided plan is worthwhile.
When to see a physical therapist
If leg pain persists, worsens, or limits you, a PT can map which nerve is involved and find the movements that calm it.
Red flags — don't wait
Emergency signs: numbness in the groin/inner thighs, loss of bladder/bowel control, or rapidly worsening leg weakness.
How a PT treats this
Care typically combines symptom-centralizing movements, nerve mobility work, walking, and graded core and hip strengthening.
