Sounds like you got a quadruple whammy for TOS...
Did the PTs , DCs, etc, do any manual trigger point work, massage, low level laser therapy, e stim, rib mobilizations, posture/body work?
I also got these things for at home use
Digital IF stim & fist had a dial EMS stim - digital controls are much easier and no accidental bumps to a higher level like with a dial adjustment.
IF stim is less prone to give zaps/zingers.
Far infrared heating pad
foam roller/ Swiss exercise ball
tennis balls for floor or wall trigger work
Most of us do have to adjust our lifestyle & activities.
I know it mentally takes a lot to readjust & come to terms with it, but it's better to avoid those flares and sometime later on, you slowly can take baby steps to more activity.
Many of us have gone thru the 5 stages of grief, with any significant loss we tend to go thru those..
