Most likely the testing will be non productive , unless it shows an extra c rib or other anatomy anomalies..
Check out our sticky threads.. the trigger point & PT info will help you get the best and faster results..
If your PT doesn't know about any of the listed things below.. find more knowledgeable PTs.
no use staying with someone that can't help you fully heal.. waste of time.. and the wrong PT CAN make you worse...
things to ask about-
top rib mobilization -- (for the lump or stuck in throat feeling)
manual trigger point release - need to check for TrPs & resolve them- can't fully loosen muscles that have a trigger point in them
forward head/shoulder posture - weight of head forward of center line puts a lot of strain on the neck & upper back muscles
follow up with home care PT suggestions
and these are very simple home things to try-

I also got a IFc stim - Amazon has many 100.00 - got mine 2006
Chiropractor used IFC stim, low level laser, hands on trigger point & top rib - plus the regular adjustments.. I was having major upper body muscle spasms at that time..
lots more in our TOS sticky threads..
