After doing some shoulder exercises, seated dumbbell press, lateral raises and such, my left shoulder is acting up. This has happened before, usually when I do regular shoulder dumbbell presses. Am I doing something wrong? Does it eventually go away? Does it get stronger? Do I just have to avoid it? Do I have to heal it? What can I do-oo? I can't be an ultimate fighter with this shoulder flaming up on me... help fitness, joint, and muscle experts. I guess a doctor maybe. Or Jesus.
