Spinal stenosis occurs when the spaces within the spine narrow, which in turn puts pressure on the nerves travelling throughout the spine. Typically, the condition develops in the neck and lower back. It is most commonly caused by wear-and-tear, from osteoarthritis or after injury. While some people afflicted by the condition do not present with any symptoms, others experience varying degrees of discomfort and pain, numbness, tingling sensations, or muscle weakness that can worsen over time.
Information. There are different kinds of spinal stenosis, depending on where on the spine the condition occurs, and it’s possible for a person to have more than one type simultaneously. The two main types are cervical and lumbar. Cervical stenosis affects the part of the spine that is in the neck, while lumbar stenosis occurs in the lower back. Lumbar stenosis is the most common form of the condition.
