Whiplash is a neck strain injury that is usually a result from a motor vehicle accident involving a car that is not moving and is hit by another vehicle from behind. With impact from the rear, the neck is forced into a hyperextended (backward) position while the seat pushes the torso forward and the head and neck backwards.

The spinal column contains open spaces that create passageways for the spinal cord and the spinal nerves. Spinal stenosis is a narrowing of (or an intrusion into) these openings.

This condition is an irritation or compression of one or more nerve roots in the lumbar spine. Because these nerves travel to the hips, buttocks, legs and feet, an injury in the lumbar spine can cause symptoms in these areas. Sciatica may result from a variety of problems with the bones and tissues of the lumbar spinal column.

Spondylosis, or arthritis of the spine, is a commonly misunderstood spinal condition.

The discs are the cushions and the low back, and there is a lot of weight that goes in those cushions and they can be injured and be herniated. They can cause no pain, but when they cause pain, they can cause either back pain or leg pain or both.
