Ahhh, those hobbies and job are a set up for TOS also.
Could be a combo of the crash and the job/hobbies.

In the useful stickys read up on posture, fascia, trigger points, Sharon Butlers stretching program for RSI & TOS {her book is in libraries},
body work - most of that is all stuff you can work on yourself or have a friend help- you can Google videos of massage, chiropractic, triggerpoint- all of those will help - I think it helps to see how it is done .

Are you having constant high pain { above a 6/7} ?

Many of the symptoms that you mentioned an expert & advanced PT person {or expert chiro that does PT modalities also} can get you going in the right direction - this is not a time for mediocre PT or rookies to be working on you...

Oh and read the chiro info about the upper cervical adjustments {also called atlas axis/c1/c2 etc} - it can get out of alignment quite easily.

Are you shoulders even & level or one higher than the other.?

Oh and the search tool is a great help for finding specific info in posts or threads.
