i was lifting off on skull crushers way too much weight, 150lbs. and got bar off of its resting spot about 1 inch and left elbow made a horrible sounding cracking noise and horrible pain shot thru and swelling started immediatly. now 2 days later swelling is about half of what it was at peak, very little pain, restricted movemement prob.from the swelling. swelling actually seems to be a little above elbow at bottom of tricep. what do you think i did. thanks...hunter
