Just recently I have had a sharp pain only when I breath in deep, right about the center of my chest right about where the center of the rib cage ends, but no numbness or anything in my arm, anyone think they might know what it means?

The only problem with asking a question like that is you will receive a random diagnosis and the fact is it could be something serious. I am not a doctor but have a healthcare background and I couldn't venture to even guess what that is because it could be so many different things.

Go see a doctor and have it diagnosed properly. It could save your life by doing so.
