--that there's alot going on in your cervical spine at the C5/C6 vertebral level, probbaly including arthritic spurring that is pressing on the spinal cord itself, the nerve roots that exit the cord and privide the starting points for the nerves of the arm, or both.

Is there any other commentary in the report?

Certainly, cervical spine problems, with the discs between the vertebrae or the vertebrae themselves, can put pressure on the spine or nerve roots an produce all kinds of neural symptoms. Nerve root pressure tends to produce symptoms in the dermatome (sensory/motor area) served by those roots, whereas pressure on the cord itself may produce symptoms anywhere from that dermatomal level downwards/

You defintiely should also post on the Spinal Disorders forum, to get some of that expertise:
