Hi Ron, with spinal stenosis you’re dealing with a tough situation where the spinal canal in the lumbar spine narrows from bony extrusions into the canal from degenerative joint disease. This places pressure on the nerves to the legs which is why you get those symptoms. Spinal decompression surgery is usually recommended for severe cases. In less severe cases, you may find relief with the McKenzie exercises. I show some of them in the Lumbar self-care rehab video. Strengthening your abs and back muscles is also a good idea.
