What is Lumbar Spinal Stenosis?

Lumbar spinal stenosis is a condition where the spinal canal narrows, compressing the nerves and spinal cord in the lower back. This often leads to pain, numbness, or weakness in the legs, especially during walking or standing. It is most commonly caused by age-related degenerative changes, such as arthritis or disc herniation. Key facts: it affects millions worldwide, and while mild cases respond to physical therapy, severe cases may require surgical decompression.
