Sciatica and Leg Pain

Sciatica and Leg Pain

About 90% of sciatica is due to a spinal disc herniation pressing on one of the lumbar or sacral nerve roots.
What is Sciatica and Leg Pain?


Sciatica pain can vary widely. It may feel like a mild tingling, dull ache, or a burning sensation. In some cases, the pain is sharp, shooting, and sometimes debilitating.

The pain most often occurs on one side. Some people have sharp pain in one part of the leg or hip and numbness. The pain or numbness may also be felt on the back of the calf or on the sole of the foot. The affected leg may feel weak.

The pain often starts slowly. Sciatica pain may get worse:

  • After standing or sitting
  • At night
  • When sneezing, coughing, or laughing
  • When bending backwards or walking more than a few meters
Common causes of sciatica include:

Spinal Disc Protrusions and Herniations
Piriformis syndrome
Osteoarthritis of the lumbar spine
Bad Posture and Spinal Alignment



Sciatica refers to pain, weakness, numbness, or tingling in the leg. It is caused by injury to or pressure on the sciatic nerve and can involve multiple lumbar spinal nerves that control the legs. Sciatica is a symptom of another problem usually related to abnormal curvature in the low back, osteoarthritis, and spinal disc protrusions and herniations

Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the lower portion of the spine and runs down the back of both legs. This nerve controls the muscles of the back of the knee and lower leg and provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot.
