What is spinal stenosis: The narrowing of the gaps in the spine or the backbone is called as spinal stenosis. This leads to pressure on the nerves and the spinal cord. 5% of cases of spinal stenosis are seen in the low back of the lumbar spine. In some cases, the narrowing of the spine leads to the compressing of the nerve root, which leads to pain in the leg.
Causes of spinal stenosis: It can be caused by aging, arthritis, trauma to the spine, spondylolisthesis and tumor of the spine
Symptoms of spinal stenosis: There is a constant pain in the back and legs as stenosis pinches the nerve responsible for sensation and muscle power. Other symptoms are numbness and tingling in the legs, frequent falling and pain while walking.
