Lumbar spinal canal stenosis

What it means

An abnormal narrowing of the lumbar spinal canal.

Symptoms of lumbar spinal canal stenosis include pseudoclaudication (pain, numbness,, or weakness induced by walking and relieved by rest; the prefix pseudo is used to differentiate this manifestation from claudication, which has similar symptoms but is caused by peripheral artery disease).
