This condition occurs when the spinal canal starts to become narrow. It could be due to herniated discs, excessive bone growth, or thickening ligaments and cartilage in the canal. Narrowing of the spine canal often infringes on the nerve root and spinal cords at the point where they push out from the cord.
Bone degeneration occurs as the body ages, therefore, the disease is seen more in people over the age of 50. Spinal stenosis affects the lumbar (lower back) spine and cervical (neck) spine exhibiting symptoms including pain, weakness, and numbness in the feet, legs, and buttocks.
