Neurogenic claudication

Neurogenic claudication (NC), also known as pseudoclaudication, is a common symptom of lumbar spinal stenosis, or inflammation of the nerves emanating from the spinal cord. Neurogenic means that the problem originates with a problem at a nerve, and claudication, from the Latin for limp, because the patient feels a painful cramping or weakness in the legs. NC should therefore be distinguished from vascular claudication, which is when the claudication stems from a circulatory problem, not a neural problem.
