pretty close - I did have 3 sets of PT sessions during the work comp part early on with the acute portion of my RSI/TOS.
Each session helped up to a point, and until I messed myself up doing heavy project at home...

I also used magnet wrist bands when I had severe RSIs (bi lateral wrist strain was the dx then) in 1999 along with MSM & a few other vitamins & supplements.
So in 2003 for the RSI/TOS combo I brought those things back into use again.
Also got a magnet necklace but it got heavy and irritating as the spasms and scalene tightness increased- same with the wrist magnet bracelets.

other things-
stopped doing almost anything with hands/arms for awhile at first as I had pain & weakness with any rotating (pronation) of the wrists.

nutrition
fluids
diaphragmatic breathing deep= belly breaths
my forearms were very affected at first so lots of ice/heat & rest for those -- but that was mostly before the whole upper body TOS stuff came into play
