Just from my own personal experience.

If you can get no, or very low symptoms with good PT and /or other therapy , there will be a time of the body getting used to the new situation.
You can't expect to go from " disabled" to back to normal activities right away.

most times TOS creeps up on us over time and the returning to a more normal state needs to be done slowly also. baby steps is what we call it.

The last thing you want to do , is too much and start the flare ups again.
Slow and easy is the best way to rehab back from it.

It may take over a year or more with PT etc, but a complete post op recovery will take the same time frame to know if it really was worth it.
