What can be causes of chest and lung pain?
Recently I started getting these sharp, needle like pains in my chest and sometimes when I inhale, I experience the same pains in my lung. A while back, I had the same pains that went from my right shoulder and into my arm. The pains only last for a little while and they arent persistent but I'm curious as to what can cause these pains. And I'm not old, I'm just a teenager.
