This symptom can feel like someone has put a belt around your chest and tightened it. It can also feel like something is pressing down on your chest or squeezing it. Your heart may be beating out of your chest. Chest pains such as these are usually why people, like yourself, attend their doctor, afraid that something has happened to their heart.
Once you have received the all-clear, the pain you are experiencing is down to breathing too fast (hyperventilation). Anxiety causes our hearts to beat more quickly than is needed. We overwork our chest muscles, which leads to the sensations we experience.
Chest pain may cause you to feel alarmed and fear that you have a heart attack. This fear often makes you panic more. As explained previously, you hyperventilate during a panic attack. When you puff regularly, you are over-breathing. You are using the chest muscles more often than usual. If these muscles are overworked too often, you will begin to feel chest pain.
