For the last two weeks I have been having twitching in my upper chest and shoulder muscle. Now the one by my shoulder has subsided but now I am getting twitching and tightening in the muscle of my upper chest by the left side of my sternum above my breast. I get it when I clench my arm to my side, swing my arms or sometimes for no reason at all. Has anyone else experienced these annoying chest twitches? And it is not like I am working out or anygthing since they started but they just keep occurring. Is this an unusual hot spot?Mary
