My step father was having numbness in his thumb. He went to the Dr. they did MRI/Xrays Dr told him he has spinal stenosis at his c4 vertebra. They made an appointment with a surgeon to discuss his options. From what I understand about S.S it is a narrowing of spaces in the spine (backbone) that results in pressure on the spinal cord and/or nerve roots.Any insight on working with this type of client?many thanksklowe
