With my various RSI's and shoulder strains- I went to a couple MCO drs, 3 personal docs & their co office mates as fill in a few times, and then the 2 IME drs {1 was OK & 1 was horrible} Oh and 1 chiropractor.
But I don't really count the IMEs drs.

The only ones that really did any sort of TOS arm checks were the chiro, and the 2 advanced PT guys.
my stuff started out as RSIs and I didn't learn about TOS till a couple yrs later..
The MDs were focused on the RSIs only.
