Mike, before I found out I had neck issues, my fingers would go numb, off balance and severe pains in neck and arms. I was actually diagnosed with rotator cup problems first. When I finally went to the doctors for severe neck pains, my doctor figured due to my age (41) it was just muscle spasms from carrying the mail. So, I got an x-ray. Within 10 minutes of me getting home, the Dr. calls and says I need an MRI and that she was sorry for not listening to me on my symptoms. Turns out I had everything wrong. Bone spurs compressing 50% of my spinal cord, one disc degenerative and one severely herniated. I also found out that I was born with a narrow spinal column. Which means less space and spinal fluid. So now, I am getting some of the issues again. I want to make sure everything is OK and to get a specialists word on whether I should keep carrying mail.
