Common in people over the age of 50, severe cervical spinal stenosis is the narrowing of the spinal column in the neck, according to WebMD. A number of factors cause the condition, including spinal instability, disk herniation, constriction of blood flow and degeneration, says Houston Methodist Orthopedics & Sports Medicine.
Other factors also contribute to the severity of the condition, including osteoarthritis and bone spurs, advises Massage Today. As a progressive disease, cervical spinal stenosis continues to get worse over time. In its advanced stages, an individual has difficulty in walking, and the disease may even prove completely debilitating. Those with the condition may also become incontinent and unable to control their bowels, notes WebMD.
