What's causing this?

The most common drivers of pain radiating from back to leg (sciatica), from most to least frequent in our clinic:

Lumbar Disc Herniation

The most common cause — a disc at L4-L5 or L5-S1 bulges and compresses the sciatic nerve root.

Piriformis Syndrome

A tight or spasming piriformis muscle in the buttock compresses the sciatic nerve as it passes underneath.

Spinal Stenosis

Narrowing of the spinal canal (common after 50) squeezes the nerve — pain increases with walking, eases with sitting.

Spondylolisthesis

A vertebra slips forward, narrowing the space where the sciatic root exits.
