Sciatica: Why Your Leg Hurts When the Problem Is Your Back

Why the Pain Is in Your Leg

Sciatica is confusing because the problem is in the back but the pain is felt in the leg. The sciatic nerve runs from the lower spine down each leg; when a slipped disc or bony narrowing presses on the nerve root, pain, tingling or numbness travels along its path — buttock, back of thigh, calf, sometimes to the foot. That radiating pattern is the signature of nerve compression.

Most Sciatica Settles on Its Own

The reassuring news: the majority of sciatica improves within a few weeks without surgery. Staying gently active (not bed rest), physiotherapy, and appropriate pain medication are the mainstays. Prolonged bed rest actually slows recovery.

When to Seek More Than Reassurance

See a specialist if the pain is severe and unrelenting, lasts beyond several weeks despite treatment, or is accompanied by leg weakness. Loss of bladder or bowel control alongside sciatica is an emergency. In persistent cases, targeted treatments or minimally invasive surgery to relieve the trapped nerve can be very effective.
