I've been a bit discouraged/frustrated on the progress of my neck/shoulder. My PT session yesterday was simply a 30 minute discussion and review of my progress. Bill showed me that I HAVE progressed, and reminded me that we can't expect a shoulder with a pathology to act like a normal shoulder. He also went into some detail about how nerve damage affects muscles, there is no doubt in his mind that my whiplash injury added even more complications to that shoulder.
In the end I am still much better off than many with shoulder issues. Even if I am, in the end, unable to gain strength in this shoulder, I need to focus on my total fitness - not just the behavior of one joint. I doubt seriously that I would consider surgery unless things deteriorate. My intense efforts at the gym are not to reach some magic "score" but to gain as much fitness as I can to take into my next stage of life.
