I have been experiencing shoulder pain. It feels like gas under my shoulder blade and then sharp pains run down my right arm to my elbow. My right side under my breast is sore as well and hurts sometimes when breathing in. I have also had a fluttering in my chest, that almost feels as though it will become a cramp, but doesn't manifest as one. I have been very lethargic for the past few months. Generally feel like poop!
