Hi, I have a sharp pain in the center of my chest when I move my arms a certain way, driving hurts, blowing my nose hurts, and laughing. I cannot shift my rib cage to reach for something. I went to the ER and I was told my heart was fine, and that it could be a pulled muscle. I'm skeptical because of the pain level. Any advice on if you think it really is a pulled muscle and if it is how do I get better? Thank you for your time.
