I've had a nagging, recurring "aggravation" with my left shoulder for the past few months. The Friday before last I was done some chest work and really jacked up my shoulder good. I went to a sports medicine doctor. He did some xrays and checked for strength in my shoulder by having my push his arms in different directions. Nothing wrong there. I am scheduled for an arthrogram and mri in a few hours, and just wanted to know if anybody else has gone through this before.
