What is the pain coming from in my chest?About once a month or two, I get a really sharp pain in the middle of my chest right where my heart is. The pain will come out of nowhere and will stay for around an hour. Two months ago, I was at my dads and the pain woke me up from my sleep. I thought it was nothing but when I tried to walk, I couldnt. I couldnt even stand up straight. Can you tell me whats wrong????
