Im a 16 years old boy.
Two days ago, I woke up with a weird chest pain
on the left side
right below the nipple.
I feel a sharp pain when I take a deep breath or let out my air completely, also sometimes when I am lying down, I feel pressure on that spot. When i try to lean toward either side, i feel pain in the same area. I don't know what is going on. I've had this once about 1 month ago, but only lasted about 4 hours.
Just a note, during that night of sleep.
