How is sciatica caused?

Sciatica is a condition characterized by pain, numbness and/or tingling in the lower back, buttocks, and legs. It is caused by compression of the sciatic nerve which runs from your lower back down through both legs. It can be caused by either a herniated disc or bone spur on the spine pressing on the nerve root (usually in the lumbar spine), or it may be caused by an injury. In some cases, it can also result from diseases such as diabetes, spinal stenosis or spondylolisthesis (when one vertebrae slips out of place). Treatment typically involves lifestyle modifications such as exercises that target strengthening core muscles to reduce pressure on the affected nerves. Physical therapy and medications may also be prescribed to aid with managing pain symptoms.
