In 2008 I had c5 disc removed. Herniated into spinal canal and pushed my spinal cord out the other side. In Dec/14 I had c6 removed, replaced with cage device, same problem as above. This time I was told there was major spinal cord damage and only time would tell what, if any, problems I would face. Twice, over past few months, my right arm has suddenly become a dead weight. No pain, I can move it but is kind of like slow motion. Lasts for approx. 15 to 20 min. Two days ago my right leg suddenly did the same thing as above for about the same amount of time. Last night, my right arm again, tonight, both legs, again same as described above. Any ideas? Is this the type of thing I should expect might happen? Should I be concerned or just let it ride? I am 52 years old Thanks, Mike
