Sciatica is a pain that occurs along the sciatic nerve. It is a common painful problem that often occurs as a symptom of another underlying condition. Characterized by pain that radiates along the path of the sciatic nerve, sciatica can significantly impact an individual's daily life and mobility.

What Are the Causes of Sciatica?
The sciatic nerve, the longest and thickest nerve in the human body, originates from the lower back and travels through the buttocks, down the back of each leg. Sciatica occurs when this nerve becomes compressed or irritated, leading to pain, numbness, and tingling sensations. Several conditions can lead to sciatic nerve compression:
Herniated Disc: One of the most common causes of sciatica is a herniated disc. When the gel-like material inside a spinal disc protrudes and presses against the sciatic nerve, it can result in pain and discomfort.
Spinal Stenosis: This condition involves the narrowing of the spinal canal, which can put pressure on the nerves, including the sciatic nerve.
Piriformis Syndrome: The piriformis muscle, located in the buttocks, can sometimes spasm and irritate the sciatic nerve as it passes beneath or through the muscle.
Degenerative Disc Disease: Over time, the spinal discs can deteriorate, leading to reduced cushioning between the vertebrae and potential nerve compression.
Spondylolisthesis: This occurs when a vertebra slips out of place and puts pressure on the adjacent nerves, including the sciatic nerve.
