Hello! Diagnosed with costocondritis. I have severe pain on my right side top ribs area. This pain started shortly after I had tendonitis in my writs and then one day my shoulder dropped down. There was no pain when my shoulder dropped but you could visually see it was very low. It went back up after a few days and then the pain began in my chest area. This pain has been on going for more than a year now. I have had cortizone injections that have helped but I still have a constant nagging pain. This pain also radiates to my right shoulder and I also have trouble with my left shoulder as well. Needless to say I cannot lay on either shoulder.
