My very first dx was bilateral wrist strain in 99.
About half way up my forearms were affected too.
A weird vibration/buzzing inside the forearms/muscles.

Thinking back it very well could have been a precursor to TOS.
Was only a yr after I had recovered {about 85% anyway} from the "wrist strain" that I began to have the shoulder/neck/upperback sx {twice} and then the final combo of all of those and more in 2003.

I think your idea of a multi pronged approach is a good one- there was a few things that one provider /tx didn't catch and another did- and boy I am so grateful for that.
