Sciatica is a condition caused by irritation or compression of the sciatic nerve, leading to pain that radiates from the lower back down through the hips, buttocks, and legs.
The sciatic nerve is the longest and largest nerve in the body, running from your lower spine through each leg. When it becomes compressed—often due to spinal misalignment, disc issues, or inflammation—it can trigger a wide range of symptoms.
While sciatica is often associated with lower back pain, the hallmark sign is radiating nerve pain that travels down one side of the body.
