I agree, stopping any offending activities is the first thing.
Have your neck muscles increased in size? could be crowding the area..

Explore our sticky threads at the top of the main tos forum page.

Does your wife know about trigger points, muscle balancing, posture correction...treating muscle spasms...
oh and maybe top rib mobilization..

If you can find a PT or chiro with a low level laser (LLLT) (aka soft or cold laser)..

I had nearly instant relief with LLLT for many kinds of pain, elbow, shoulder, foot, wrist, low back... with chiro.

You might get a better price break with an expert chiro than PT, but doesn't hurt to ask..
