Re: neck pain
The ddd is extremely common. Pretty much "normal".
Between the C5 and C6 vertebrae, something is impinging on the spinal canal. Note that it's "mild" (the normal range of adjectives is minimal-mild-moderate-severe) and that the CANAL is affected, but not the CORD within the canal.
At the C6-7 level, friction between the vertebrae and the disk is causing bone spurs to grow backward into the spinal canal. They've grown enough to not only compress the canal but to press on the left front of the cord. Once again, "mild" is used to describe the problem.
Any symptoms apart from neck pain?
