Most people get low back pain at one time or another. Low back pain is a symptom of a problem. One common cause of low back pain is a condition called spinal stenosis. Spinal stenosis is a narrowing of the spaces in the backbone, or spinal column. This narrowing can put pressure on the spinal cord or nerve roots. The spinal column is formed by the bones of your spine, called vertebrae. The vertebrae have a hollow core. When stacked upon each other, they form a canal that protects and supports the spinal cord. Nerves, called nerve roots, branch off from the spinal cord through spaces between the vertebrae and lead to different parts of your body.
A concussion is an injury to the brain caused by a blow to the head, or by striking the head on another object. It may result in loss of consciousness or confusion, but the effects usually resolve in a few hours or days. This video explains what happens during a concussion, how it should be treated, and what preventive steps to take.
The vertebrae in your spine are cushioned by soft disks. When one of the disks in your neck—the cervical area of your spine—ruptures, the result can be neck pain. Watch this video to find out the possible causes and recommended treatment.
