Sciatica refers to irritation, compression, or inflammation of the sciatic nerve—the body’s largest nerve—which travels from the lower back through the hips, buttocks, and down each leg.

Rather than being a condition itself, sciatica is a symptom of an underlying mechanical issue affecting the lower spine, pelvis, or surrounding tissues.

Sciatica often occurs when the sciatic nerve or its nerve roots are irritated by spinal joint restriction, muscle tension (such as piriformis syndrome), disc bulges or herniations, pelvic imbalance or poor biomechanics.

Osteopathic treatments work to improve mechanical function and reduce nerve irritation by:

Supporting posture and movement retraining

Restoring spinal and pelvic mobility

Reducing muscle tension and compensation patterns

Improving hip and core mechanics

Most cases of sciatica improve with proper mechanical treatment, movement correction, and activity modification. Prevention often includes mobility work, strength training, and posture awareness.
