Whats lumbar spinal stenosis?

Let us help: Lumbar stenosis, the spinal nerve roots in the lower back are compressed, or choked, and this can produce symptoms of sciatica -- tingling, weakness or numbness that radiates from the low back and into the buttocks and legs -- especially with activity.

A small spine canal: When the overall cross sectional area of the spinal canal in any region of the spine for the neural tissue to be compressed leading to clinical symptoms/findings. This can be:congenital basis, degenerative one with aging or a result of a acquired reason like: cyst, tumor, hematoma, abcess, fracture or disc hrniation or a combination of above. Not all people with small canals get symptoms.

Narrowing: A narrowing or "pinching" of the nerve canal.
