My left side is killing me. My shoulder, my arm my chest it all hurts. The top of my shoulder is really tense. You can feel how hard it is. My bisep is really sore and tight. Its causing me alot od anxiety because my brain keeps going to heart attack. But I know its just anxiety and muscle tension. Which worrying about it is making it all worse. My muscle feel really hot and cold at the same time. I'm such a mess right now. I'm just laying in bed crying because I don't know what else to do with myself.
