Sciatica

Sciatica is a painful condition caused by compression, irritation, or pinching of the longest nerve in the body. Various factors, including poor posture, disc bulge, and muscle spasms, can cause it. Physiotherapy can help reduce pain and improve spinal health through core-strengthening activities, techniques like TENS and ultrasound, and teaching appropriate posture and dos and don'ts. Diagnosis is based on symptoms and a physical examination, with X-rays and MRIs sometimes needed for serious cases.
