Do you have any ideas on how you acquired TOS?
Accident/injury, sports, related, repetitive or desk work?

I didn't have surgery , but at one point my hands totally stopped working for awhile, repetitive assembly job 10 hr days..total of 15 yrs.
My pulse stopped with arms outstretched, hands would turn white and red when lowered. I couldn't sleep much due to elbows sensitive to pressure of mattress, had to pad and wrap them and had to sleep on my back with arms straight along body.
I didn't have numbness or extreme pain though.

I did have symptoms moving from hands, to arms ,to neck ,to upper back, to elbows, to wrists. MD & PTs kept chasing each area vs looking at the whole picture..
Most of my sx were due to muscle imbalances and myofascial adhesion/sticky tissues. And later on when I had severe spasms it pulled my top ribs up and they got stuck in that position.. more symptoms and limitations..
but kept searching and I found a PT teacher who found my top ribs were raised and dropped them down quite easily.. Instantly felt relief.
Also at same time my chiro was doing a very helpful mix of therapies too. I told him of the top rib fix then he followed up on that when needed.

So, my point is, soft tissue problems can really do a number on us.
Sometimes surgery isn't needed , just some expert treatment providers that understand how the body can get messed up , and that they have the skills to remedy it.
Of course it did take time (2 yrs approx, some wasted time due to work comp rules etc) and I was off work when treatment really started to make a difference.
I know that is not an option for everyone.

I can do most activities now as long as it isn't too repetitive or many day in a row.
Cool/cold weather affects me in a negative way but feel pretty good in warm weather.
