Hi,
It's hard to give a definite answer to that question, there are so many variables to consider.

If you've had x rays & MRIs to rule out any c spine issues & anomalies, expert PT is a good place to start.
It isn't a quick fix, and will take longer if you are still working, but is always worth a good try. Lots of "homework" self care is needed too.

Finding the best PT that you can is the quickest way to see improvements.
Poor PT can set you back and even make you worse, so if they don't work with you and evaluate you at every session to see how you are progressing , or not, and making adjustments to the plan, then they are probably not the best fit.

If in the past you've had any whiplash, sports, falls, hits or other upper body injuries, then perhaps an expert chirpractor or bodywork/alignment type therapy to make sure all is good there.

Those minor traumas over time can cause adheisons and restrictions in the fascia, which doesn't show up in most "tests".
Sharon Butler explains the role of fascia very well.
