Lumbar Spinal Canal Stenosis Causes Back, Leg Pain

THE LUMBAR SPINAL CANAL is the space in the lower spine that carries nerves to your legs. It is very narrow and gets even narrower if the bone and tissue around it grow over the course of many years. This narrowing is called “stenosis.” Lumbar stenosis is usually a disease of the middle-aged and the elderly.

AS THE lumbar spinal canal narrows, the nerves that go through it are squeezed. This squeezing may cause back pain, leg pain, weakness and numbness.
