I was jumped on an hour ago and while trying to push them off they grabbed my arm and twisted it weirdly and the middle of my forearm cracked loudly and it hurts when I move, bend elbow or wrist, put any pressure, and move my middle, ring and pinky finger. It's not impossible to move and there's no serious bruising, but it hasn't let up any and I've pulled muscles and tendons a lot, but nothing like this. Do tendons or muscles make cracking sounds? I'm only 17 and nobody is going to take me to a doctor, but I need to know if I should get someone here to take me.
