Pain that radiates from your lower (lumbar) spine to your buttock and down the back of your leg is the hallmark of sciatica. You may feel the discomfort almost anywhere along the nerve pathway, but it's especially likely to follow a path from your low back to your buttock and the back of your thigh and calf.

The pain can vary widely, from a mild ache to a sharp, burning sensation or excruciating discomfort. Sometimes it may feel like a jolt or electric shock. It may be worse when you cough or sneeze, and prolonged sitting can aggravate symptoms. Usually only one side of your body is affected.

Some people also experience numbness, tingling or muscle weakness in the affected leg or foot. You may have pain in one part of your leg and numbness in another.

When to see a doctor

Mild sciatica usually goes away given time and patience. Call your doctor if self-care measures fail to ease your symptoms or if your pain lasts longer than a week, is severe or becomes progressively worse. Get immediate medical care if:

  • You experience sudden, severe pain in your low back or leg and numbness or muscle weakness in your leg
  • The pain follows a violent injury, such as a traffic accident
  • You have trouble controlling your bowels or bladder
