What Is Spinal Stenosis?

Spinal stenosis is a condition in which the spinal canal narrows and pinches the nerves, resulting in back and leg pain.

Spinal stenosis often occurs in older adults, although younger people who are born with a small spinal canal may also develop symptoms. Aging can cause the ligaments (tissues that connect the spine and bones) to become thicker and the discs between vertebrae to break down. Growths called bone spurs may occur on bones and into the spinal canal. A lack of blood flow to the lower spine can also be a factor.

Symptoms of spinal stenosis include pain and difficulty walking, as well as numbness, tingling, a sensation of hot or cold, weakness or a heavy, tired feeling in the legs. A person may also experience clumsiness or frequent falls. If you notice any of these symptoms, talk with your doctor. He or she may recommend pain medication or corticosteroid injections to reduce swelling and pain, posture changes, physical therapy, or weight loss. Surgery may also be an option.
