Where the breast join together in the middle bit i just had a really bad paid it was really tight am 40, f, is that a heart attack sign pain has stop?

Maybe: Pain in this area of the chest can represent pain from a heart-attack or it can be angina (pre-heart-attack pain) or it can be pain from your stomach or other things. Cardiac chest pain frequently feels like pressure or a weight on your chest. If you have pain like this that happens when you exert yourself climbing stairs or walking, etc, you need to see a doctor ASAP. Best wishes!
