Well, I got the brachial plexus MRI back. Results:

1) There is no evidence of mass or area of abnormal enhancement in the region of the right brachial plexus. Soft tissues are normal in signal. There is no evidence of an apical lung mass.

2) Moderate disc degeneration at C5-C6 and C6-C7 and there is posterior osteophytes and mild bulging of discs which slightly narrow the ventral thecal sac. There is no mass effect on the cervical cord at the C5-C6 or C6-C7 levels.

So it would seem that the brachial plexus is fine.

I didn't realize this would pick up on the c-spine. I find it "interesting" that the use of the word "moderate" was used here for the disc generation. I've had a c-spine MRI before and it spoke to more of a "mild" situation and the neurosurgeon basically kicked me out of their office.

I wonder if C5 - C7 is producing this kind of elbow pain and tingling in my pinky? Wonder if it's worth a steroid injection in this area.

Only other exam at this point is an EMG. Would this pick up nerve compression that's taking place beyond the brachial plexus? From the shoulder down the arm?

I tell you I'm confused. I've got serious pain but MRIs left and right say nothing (unless there's really something going on in the c-spine).
