Thats a tough one. We are all stubborn about this stuff. If you can make it through your training, working around this stuff, I’d say go for it. Thing is, you need to be honest with yourself. I think its easy to pretend its not an issue when it is an issue. If pushing forward is going to even slightly have the potential to cause further issues, I’d say reconsider getting some work done on it. You just don't want to make things worse. I have had some major tendonitis issues over the years and with time, I’ve noticed muscle imbalances because of them. The muscles fire differently due to alterations in how I conduct an exercise on one side vs the other. So just keep that in mind. We all get hurt brother. Some injuries are better than others. Im not sure how well they can fix your specific shoulder issue but if theres a good chance for a full recovery, don't hesitate to invest the time. This is your life. It’s your body. You want to keep it running well for a long long time.
