What causes Sciatica?

Sciatica is usually linked to a problem in the spine that irritates the sciatic nerve, which is the largest nerve in your back and continues down through your buttocks and your legs. This nerve gives and receives information to almost the entire lower half of the body.

When the nerve gets irritated, it no longer functions correctly, leading to symptoms such as: pain, weakness, tingling, a burning sensation and loss of balance. These symptoms can range from mild to severe. 

The most common causes of sciatica are:

  • A spinal disc that is herniated and bulging
  • Spinal stenosis
  • Spondylolisthesis
  • Pregnancy
  • Being overweight
