Question

Sciatica (low back pain radiating down leg due to compression) most commonly involves which lumbosacral nerve roots, and what are the symptoms?

Answer 1

Sciatica commonly involves the L4/L5 or L5/S1 nerve roots, causing back pain that radiates down the leg with possible numbness and weakness.

Step-by-step explanation:

Sciatica is a painful condition that results from the inflammation or compression of the sciatic nerve or any of the spinal nerves that contribute to it. This condition most commonly involves the lumbosacral nerve roots, specifically L4/L5 or L5/S1. The symptoms of sciatica may include lower back pain that radiates down the thigh and into the leg, possible numbness, muscle weakness, and a burning sensation along the nerve pathway. The specific symptoms can vary based on the exact root compression location.
