What Are the Primary Causes of Sciatica?
Sciatica is often caused by a herniated disc, spinal stenosis, or bone spurs that irritate the sciatic nerve.
Explanation
Sciatica is a condition that causes pain along the sciatic nerve, which runs from the lower back down through the legs. The primary causes of sciatica involve pressure on the sciatic nerve, which can happen for several reasons.
Herniated Disc: This is the most common cause of sciatica. It occurs when a disc in the spine bulges out and presses on the nerve.
Spinal Stenosis: This is a narrowing of the spinal canal, which can put pressure on the nerve roots.
Bone Spurs: These are bony growths that can develop on the spine and compress the nerve.
These conditions can cause pain, tingling, or numbness in the leg. Understanding these causes can help in managing and treating the symptoms effectively.
