A narrowing of the open spaces in the spine.
Spinal stenosis can put pressure on the spinal cord and the nerves that travel through the spine. It mostly affects the neck or lower back. The most common cause is wear-and-tear changes in the spine from arthritis. Most people with the condition are older than 50.
Some people with spinal stenosis have no symptoms. But symptoms can come on slowly and get worse over time. They can include pain, tingling or weakness in a hand, arm, foot or leg. Spinal stenosis also can cause problems with the bowel or bladder.
Treatments include anti-inflammatory medicines to relieve the swelling and pain. Physical therapy might help. Other treatments are steroid shots and surgery to make more space in the spine.
