My husband was told that his diagnosis of spinal stenosis requires immediate surgery. His symptoms have included raising his right arm with pain and tingling on his fingers for the past several months. His MRI was taken today and sent to HSS in NY . The dr. recommended immediate surgery. We have a unique situation,living on the end of Long Island, and our home is rented at the end of this month. Can this surgery be postponed for at least a few weeks? How fast does stenosis evolve?
