I would drop that PT person ASAP!
You don't have to stick with anyone that is not helping you and for sure ones that are causing you more pain..
*It is not the PT's place to decide what or what isn't causing you pain..*

Tell the doc in change what is happening..

It may be trickier if work comp is involved , but get an wc atty on your side if you don't have one for your claim yet and I sure hope you have your own drs to get best care..

Which RSD symptoms do you feel don't match up for you?

There is another possibility may not be , but I want to mention it just in case.
Since you mention rotator cuff surgery, I'm not sure how that injury happened with the dog attack.
But if there was a fall or hard yank or jolt to the arm/shoulder/neck??
Some of what you re experiencing might be thoracic outlet syndrome TOS for short.
Another kind of rare thing like RSD unfortunately.. You need experts or extremely knowledgeable drs & PTs to get a dx as well as correct tx..
It can be caused by impinged nerves and/or blood flow in the neck/shoulder /collarbone areas, even the pec minor can play a role..
Often there will be muscle spasms , trigger points in the neck & upper back areas.

If it is TOS- or something like it - the weights/strengthening PT is doing is a bad thing..it will make it worse.
but passive work on shoulder posture is a plus. meaning letting gravity do the work..
I'll put some links for you to read thru- so you can see if it fits a bit or not at all..
