Understanding Spinal Stenosis

Spinal stenosis is a common and often age-related condition characterized by the narrowing of the spaces within the spine.

What is Spinal Stenosis?

Spinal stenosis is a common and often age-related condition characterized by the narrowing of the spaces within the spine. This narrowing can put pressure on the nerves and spinal cord, leading to a range of symptoms that affect mobility and overall quality of life.


  • Pain or Numbness: Discomfort in the affected area, often radiating down the legs or arms.
  • Weakness: Reduced strength in the limbs.
    Tingling Sensations:
  • Unusual sensations, such as tingling or a “pins and needles” feeling.
  • Difficulty Walking: Challenges with balance and coordination, particularly in lumbar stenosis.

Causes of Spinal Stenosis?

1. Age-Related Changes:
Degenerative changes in the spine over time, such as the thickening of ligaments or the development of bone spurs.

2. Herniated Discs:
Discs between the vertebrae may herniate, contributing to spinal canal narrowing.

3. Injuries or Trauma:
Previous injuries or trauma to the spine may increase the risk of stenosis.

4. Genetic Factors:
Some individuals may be genetically predisposed to developing spinal stenosis.
