I know RSD can happen from surgeries or even a minor injury, yours showed up after the surgery right ?

I don't know if it would show up so suddenly though??
It almost makes me wonder if you might have been misdiagnosed or if the surgery had a complication.

I think i would see a different doctor for a second opinion- take the surgery notes and any films or test results with you.

I don't have RSD myself , I have TOS {thoracic outlet syndrome} but I read many of the forums and most will suggest a second opinion espcially if post op there is still some problem.
the reason-
>The original surgeon may not want to admit that a mistake might have been made.
