Sciatica is a type of pain caused by the irritation or inflammation of the sciatic nerve. It is usually caused by a compressed sciatic nerve in the lower spine.
Sciatica happens when the sciatic nerve becomes pinched by a herniated disk in your spine or by an overgrowth of bone (bone spur) on your vertebrae. Sometimes the nerve can be compressed by a tumor or damaged by a disease such as diabetes.
There are some risk factors to develop sciatica-like age-related changes in the spine such as spinal stenosis. Spondylolisthesis. Obesity by exaggerating the strain on your spine. Sciatica may also occur during pregnancy a job that requires you to twist your back, carry a heavy load or drive a motor vehicle for long periods. Prolonged sitting or sitting in an awkward position or on your wallet. Diabetes. Or neuritis.
The sciatic nerve is the longest nerve in the human body running from the spinal cord through the buttocks and down each leg right below the knees.
