I have had pain on the right side of my chest for the past 3 weeks. It came on suddenly and feels like my chest is bruised. It hurts when I inhale, cough, sneeze or move the "wrong" way. Today it is really bothering me, I am feeling a lot of pressure and throbbing. Can someone give me a clue as to what this may be? I have a doctor's appt. thurs, maybe I can give my doctor an idea. Thank you
