My husband had numbness and tingling in the right leg from the knee down two weeks ago and saw a neurologist and an orthopedist. Neurologist cleared him and orthopedist said stenosis of lumbar from xrays. Today he began getting waves of numbness in his arms and side of back. No nausea, sweats or dizziness, no headache, or difficulty with speech and no chest pain. Going back to doctor tomorrow. what should we do ? Particularly right arm.
