Well just when I was getting worried about the reprocussions of my bad shoulder... boom... it fucks me. I was training shoulders today, doing some front arm raises, and my shoulder gave way and when the weight fell, it jerked my arm and pulled a muscle in my upper back. So now it's very stiff, and I have a hard time turning my head. So now I'll be down for a few days. It's very frustrating to want to go work out so bad, and know that I can't. I hate this. But it could be worse. This will pass in a few days. For now, I'm just icing it, and taking ibuprofen to ease the pain.
