Hi there. I m 13, turning 14 in October. And recently I ve been having pains in my chest . They are sudden sharp pains, and they feel like a bone poking into my lungs and if I moved, the pain would worsen. I try not to breathe so hard and freeze there for a while until the pain went away. The pains usually last for half a minute, not too long. As long as I don t move, the pain will lessen, then slowly go away. I used to have pains like that when I was smaller too, but that was only when my sister tickled me and I laughed too hard. But recently these pains have become more and more frequent. Does this trigger any alarms?
