Yes, I do think your should have X-rays of your neck taken, including (important) "obliques".
Neck pain is common and frankly we don't generally get too excited about it, unless it's lasting more than a few months. Research shows if it lasts for 6 months, you've got it for ever, no matter what the treatment.
But neck pain that radiates to your arm, in this case very specifically to the C6 dermatome, with certain movements of the neck is far more important.
There's something happening in your lower neck, probably in the UncoVertebral Joint Luschka
at the C5-C6 level. But's that an educated guess obviously.
It's great that you haven't lost strength. The most commonly affected muscle is the triceps. How is it with push ups? Does that arm tire faster?
Jeff, this might go away with a few weeks' rest but to my mind we need a diagnosis. What's going on? Otherwise it'll simply start again next time you start training, and then we're two months closer to that six month deadline. Find a good chiropractor
is your next stop.
