Causes, Symptoms of Spinal Stenosis

Young people who have had a spine injury or have a narrow spinal canal are also at risk of spinal stenosis. This condition can also result from diseases such as arthritis and scoliosis. The symptoms of this ailment can begin to appear gradually, while in some cases it might not show up at all. Read on to know more about this condition.
The narrowing of the spaces within your spine can lead to a condition known as spinal stenosis.

The narrowing effect leads to pressure build-up on the nerves that travel through the spine [3]. This condition ideally occurs in the lower back and the neck [2] . When the nerve roots and spinal cord become compressed, it causes a pinching of the spinal cord and nerve roots leading to cramping, pain, numbness and weakness [4] . Depending on the location of the narrowing, the symptoms can be felt in the lower back and legs, neck, shoulder or arms.

Types Of Spinal Stenosis
The type of spinal stenosis is decided based on the affected region of the spine.
The following are the two main types of spinal stenosis:
Cervical stenosis: In this, the narrowing occurs in the cervical part of the spine in your neck [5] .
Lumbar stenosis: In this, the narrowing occurs in the lower back region of the spine [6] .

Causes Of Spinal Stenosis
Some people have a small spinal canal from birth [7] .
This condition is called congenital stenosis. However, the primary cause of this condition is age-related. This kind is called acquired spinal stenosis.
The following medical conditions can cause spinal stenosis [8] :
Paget’s disease Inflammatory spondyloarthritis
Spinal tumours Osteoarthritis and bony spurs
The following increases the risk of developing spinal stenosis [8] :
If you are above 50 years of age
If you are born with a narrow spinal canal
If you are a female
If you have had a previous injury or surgery of the spine

Symptoms Of Spinal Stenosis
For people who experience symptoms with this condition, they usually begin to show gradually while worsening over time. Symptoms vary depending on the location of the stenosis and the nerves that are affected.
The following are the symptoms of the cervical spinal stenosis [9] :
Neck pain
Problems with walking and balancing
