My husband is having tingling and pain in his hands and wrists, mostly when he is sleeping. It is severe enough to wake him several times a night. Two different doctors are debating whether it is carpal tunnel or whether he has a pinched nerve in his spine. He has had an MRI and is scheduled for a nerve conduction test. I need to know what questions we should be asking these specialists. My husband is very nervous about this and very fearful that it will mean surgery. Oh, he is a long-time controlled diabetic, as well. Any suggestions?
