For about a year or so I have been randomly getting sharp chest pains. They can happen at any time even if i m just laying down in bed doing nothing. When this happens i cannot breathe, if i try the pain increases. I cannot move either, i have to be still and not breathe otherwise i feel as though i m being stabbed. These can happen anywhere from a few times a week to multiple times a day. The pain is on both sides of my chest and sometimes in the back.
