Spinal Stenosis 

Spinal stenosis is a narrowing of the spinal canal, caused by osteoarthritis, disc degeneration, thickening of the ligaments, injury, and other causes. Genetics also play a role in the development of spinal stenosis. 

Symptoms include back, neck, and leg pain, including numbness in the posterior, thighs or calves, and difficulty maintaining balance while walking. Although painful, the symptoms of spinal stenosis can be alleviated with postural supports and pressure-relief products.
