Hi everyone. I'm Guy, 66 yrs old and just had neck surgery, C4C5C6C7 ACDF. This because of constant neck & shoulder pain. Surgery supposedly successfull but have lost the ability to lift my left arm from the shoulder. Can bend up at elbow but difficult. have been told PT and 3-6 months. Anyone that can give me some hope. I'm afraid I've lost the use permanently and very depressed at the thought.
