I didn't have any surgery.
But at my worst, my hands lost all fine finger use, and arms, neck & shoulders had constant burning tension, with many spasms and triggerpoints.
Blood flow to arms/hands was only cut off and an issue if arms were raised up to shoulder level or higher.

After 2.5 yrs and lot of good PT, expert chiropractor & tons of self care and posture awareness I was able to start doing strenuous activities again.
My top rib had got raised & stuck , so getting than dropped back down was a big improvement, but didn't realize/figure it out for a while..top PT guy fixed that. then chiro maintained it.
Slowly and work up to longer times and back off if pain happens./increases.

I was in my 40s then, now 59, but still can stack hay, drive tractor, rototill, shoot some baskets, carry grand kid around.
