Spinal Stenosis and degeneration.
The cause of spinal stenosis is commonly associated with aging, although it may occur in younger people who develop a curvature of the spinal canal or suffer a spinal injury. The facet joints (small stabilizing joints located between and behind vertebrae) tend to get larger as they degenerate, and can compress the spinal nerve roots in the lower back, often producing symptoms of pain, especially with activity. This all adds to the degenerative arthritis in the spine
Generally, patients with spinal stenosis seem to be comfortable sitting, but standing upright further decreases the space available for the nerve roots and can block the outflow of blood from around the nerve. Congested blood then irritates the nerve, causing pain. It is important to note that spinal stenosis rarely causes nerve damage and surgery is almost always elective. One needs to be closely examined, monitered and treated by a medical practitioner for all back problems.
