Hi my name is Easton, and for the past 5 days I ve been having chest pain. It started Wednesday, it was just a sharp pain at first and continued through out the day, Thursday was the worst day, sharp pain as I turned my head to the right or if I lifted my left arm and pain in the back, it felt as if my chest was swollen. And as I took deep breaths the pain worsened. It s now Sunday and I still have sharp pain on the left side of my chest. It is also hard to sleep at night because the pain. I am only 24 should I be worried? And what could it possibly be?
