went to the doctors today, I have always had a little pain in my right shoulder. Well today it was pretty serious during my chest workout. so i went and seen my doctor. He took x rays and examined it and said that the loud noises i was hearing were just the tendons moving across the bone. He had me do some tests with arm movement and strength and said it shouldnt be too serious. But refered me to another specialist if i was worried about it. Do you guys think i should go see him and pay 2200 for an mri, or is this common?
