Sciatica is pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg and usually affects only one side of your body.
Sciatica most commonly occurs when a herniated disk, bone spur on the spine or narrowing of the spine (spinal stenosis) compresses part of the nerve. This causes inflammation, pain and often some numbness in the affected leg. Pain varies from a mild ache to a sharp, burning sensation or excruciating pain. Some experience numbness, tingling or muscle weakness.
For patients with severe sciatica symptoms and associated with significant leg weakness or bowel or bladder changes, surgery may be an option for you.
