What Causes A Painful Prick In My Chest?

Hi, well lately I ve been having wierd sensations on my chest, it happens frequently. I m sitting down doing stuff then i slightly move and a feel a painful prick in my chest or a little lower (around my lungs?). Sometimes it happens and i just ignore it, but a couple of days ago i was sitting on a bean bag with my laptop, then i got up off the bean bag and u felt an extremely painful prick, i thought the pain was going to go away like it always does but then i inhaled and it felt like my lungs were getting jabbed at with a needle! That happend every time i inhaled for about 5 minutes then the pain went away, do you have any idea what it is?
