Thanks Tshadow. I was just in today for my MRI results and to have the EMG/ SSEP (neck down test) run and all results look good aside from direct shoulder joint problems (i.e. mild arthritis, bursitis, minor tendon damage). Also I have 4 disks showing mild degenerative disk disease aside from the surgically repaired disks in my lower back. Nothing noteable in the brachial plexus or C-spine so my Neuro made a few suggestive comments about my vascular surgeon's thoroughness and suggested I return to my Ortho if I wish and if he doesn't find anything conclusive he'd like me to go to the Mayo clinic down in Rochester and have the whole battery of tests rerun by the specialists there. Nothing's ever easy is it?

Thanks for all of your help folks. I'll pass along an update when I have one and I'm still open to any suggestions.
