Understanding Sciatica

Sciatica

Sciatica is a condition caused by irritation, inflammation, or compression of the sciatic nerve. The sciatic nerve is the largest nerve in the body and runs from the lower back through the buttocks and down each leg.

Sciatica commonly causes pain that travels from the lower back or buttock into the leg. It may develop suddenly due to a disc injury or gradually because of age-related changes in the spine, spinal narrowing, or other conditions affecting the nerves. Identifying the underlying cause is important for choosing the right treatment and preventing symptoms from becoming persistent.

Common Causes of Sciatica

Sciatica can have several possible causes, including:

Bulging disc
Spinal injuries
Spondylolisthesis
Lumbar spondylosis
Lumbar spinal stenosis
Slipped or herniated disc
Degenerative disc disease
Bone spurs affecting spinal nerves
Age-related changes in the spine
Muscle or soft tissue conditions affecting the sciatic nerve

How is Sciatica Diagnosed?

A detailed clinical evaluation is performed to identify the underlying cause of sciatica. Your specialist may assess your symptoms, spinal movement, muscle strength, reflexes, sensation, and neurological function.

Depending on your symptoms and examination findings, diagnostic investigations such as X-rays, MRI, CT scans, or other imaging tests may be recommended to evaluate the spine, discs, and affected nerves.
