Hi, I ve been pitching (softball) more than usual the past four days, and today I have sharp chest pain which worsens when I take in a deep breath and shoots into my upper back. I also have back, neck, arm, and shoulder pain, but that s most likely from the windmill motion and could just be soreness. I ve been pitching for eight years now and this is the first time I ve had chest pain like this. I just wanted to make sure I wasn t dying.. ha.. Thank you for your time.
