Common Causes of Radiating Pain

Sciatica & Sciatic Nerve Compression
Sciatica is caused by irritation of the sciatic nerve or its roots in the lower back, producing sharp or burning pain down the buttock and leg. It may also involve tingling, numbness, or weakness in the foot. Conditions like lumbar disc herniation, spinal stenosis, or piriformis syndrome often trigger this.

Lumbar & Cervical Disc Herniation (Slipped Disc / Radiculopathy)
A herniated disc can compress nearby nerve roots, causing pain to radiate into the leg or arm. Lumbar disc herniation often affects the lower back and legs, while cervical radiculopathy impacts the neck, shoulder, and arm.

Spinal Stenosis & Foraminal Stenosis
Degenerative changes or narrowing of spinal canals can compress nerve roots, producing pain, tingling, or weakness in the limbs. Foraminal stenosis specifically affects the nerve exit points.

Piriformis Syndrome
Tightness or inflammation of the piriformis muscle can compress the sciatic nerve, mimicking sciatica and causing buttock and leg pain.

Degenerative Disc Disease & Spondylosis
Age-related disc degeneration and spinal joint changes can compress nerves, leading to chronic radiating pain in the arms or legs.

Peripheral Nerve Entrapment & Sacroiliac Joint Dysfunction
Compression of nerves in the wrist, elbow, or hip (carpal tunnel, cubital tunnel, meralgia paraesthetica) and sacroiliac joint dysfunction can also produce radiating pain along the limbs.
