Stenosis is a Latin word that simply refers to a tightening or a tightness. Lumbar stenosis means a tightening or a tightness around the nerves in the lower lumbar spine. Lumbar stenosis can present with symptoms of radicular leg pain. So lumbar radiculopathy or sciatica. It can also present with what's called neurogenic claudication, which means a sensation of leg heaviness or tiredness with prolonged activities such as standing or walking. Lumbar stenosis typically occurs as a result of degenerative changes in the lumbar spine, like a degenerative disc disease or facet arthropathy, arthritis of the facet joints in the lumbar spine, and is a gradually progressive problem that starts usually in the fifth or sixth decade of life and gets worse as time goes on.
