I have right chest pain(at one point along the sternum) for last 10 months.I got 1 MRI thorax, 1  MRI sternum, 1 CT, 2 XRay but didn't find anything except mild sternoclavicular joint subluxation.I still have the chest pain.I checked my chest by touching and could feel that that one of the rib joint attaching to sternum comes up when I move my right arm.Seems to be coming up a little and also that is what hurts me like a burning sensation. no cough, no breathlessness. The pain persists all 24 hrs except when I lie down.
