Good advice there. I'd look in to this one more thoroughly. I have similar sx but my nerve conduction/ emg test were normal. Eleven years later neurosurgeon requested they were redone before putting in a spinal cord neurostimulator. Of course, they found long thoracic nerve palsy and chronic dennervation of anterior serratus muscle! Apparently, it's commonly overlooked as they do not test far enough down the nerve tree. Too late for me to look at any remedial surgery, though may have been from the start as likely mechanism was traction.Good luck, booklover
