Occassional stabbing chest pain.
I'm a 21 year old male, who's in average shape. I was wondering if my occasional stabbing chest pains should be something to worry about. About 2-3 times a week, I get these stabbing chest pain in the left part of my chest. It usually happens after driving my car, or lifting heavy objects. It hurts very badly when I take a deep breath, the deeper the breath the more it painful it becomes. The pain is like someone jabbing me with a toothpick, but it soon goes away after 5 minutes and I get no other symptoms.
