Spinal stenosis symptoms include neck or back pain; numbness, weakness, cramping or pain in the limbs; pain going down the leg; and foot issues. It’s caused by a narrowing of the spinal canal that puts pressure on the nerves and spinal cord. It’s most common in people over 50, though injury or a genetically smaller spinal canal can lead to issues in younger people, too. Arthritis and scoliosis also can cause spinal stenosis.
