What is Sciatica?
The definition of Sciatica means pain that flows along the path of the sciatic nerve, which begins from your lower back through your hips and buttocks and down each leg. Generally, sciatica affects only one side of your body.
Sciatica happens when a herniated disk, bone spur on the spine or narrowing of the spine (spinal stenosis) applies pressure on part of the nerve. This causes inflammation, pain and often some numbness in the affected leg.
The pain of sciatica can be severe, but in most cases, it can be treated even without operation in a few weeks. People who have severe sciatica that is related with significant leg weakness or bowel or bladder changes might be candidates for surgery.
