Lumbar spinal stenosis is also known as inflammation of the nerves emanating from the spinal cord. Neurogenic means that it originates from the nerve. Claudication means cramp and originates from latin.
Patients report cramping and weakness of either 1 or both limbs. Limping can be observed and the pain reported tends to be high on the pain scale. Vascular claudication also causes similar symptoms however upon resting the patient reports that the pain reduces quickly unlike a stenosis of nerve origin.
