What Is Spinal Stenosis?

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

In adults 50 years of age and older, the risk of developing spinal stenosis increases. Younger people who are born with a small spinal canal may also develop symptoms. Aging can cause the tissues that connect the spine and bones (ligaments) to become thicker and calcified. The disks between vertebrae break down. Growths called bone spurs may happen on bones and into the spinal canal. All of these conditions tighten the spinal canal. This causes spinal stenosis.

Symptoms of spinal stenosis include pain and trouble 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. Often, bending forward will lessen the pain, such as by leaning onto a shopping cart at the grocery store. If you notice any of these symptoms, talk with your healthcare provider. He or she may recommend pain medicine or corticosteroid injections to reduce swelling and pain, posture changes, physical therapy, or weight loss. Surgery may also be a choice.

Surgical treatment for spinal stenosis is considered after nonsurgical remedies have not improved symptoms, and when the benefits of surgery are greater than the potential risks. In some cases, surgery may be an urgent matter due to the development of severe weakness or loss of bowel and bladder function.
