Dead Arm?

My arm (Upper Forearm, elbow, in between elbow and shoulder, and shoulder) has been tired and achy for the past couple of days, and I haven’t thrown since Saturday. Also, when I was throwing on Saturday, I was feeling pain in my elbow and some sort of a painful “crack” behind and below my shoulder. Can someone tell me if they know what this could be? Is this normal? Has anyone experienced this?


A “crack” could be caused by some swelling or inflammation. If that is the case, then the question is what is causing that. Probably better go see a doctor.
