Hi for the last year or so I've been having chest pain that I put down to indigestion it starts in the centre of my chest an radiates outward it can last from a few minutes to a few hrs but twice now this has been accompanied with pain down my arm that stops at the elbow, I sweat a lot doing things like walking now I've been dizzy a fair bit over the last few weeks an I feel as tired as I did while
pregnant but I'm not. I'm worried it could be my heart? I'm a smoker of about 15 a day
