At 34 years old, how concerned should I be about chest pain that goes into my arm?
It's important for you to see a doctor immediately. The symptoms you're describing sound like classic angina, resulting from coronary artery disease. It could be something else, but you need to be evaluated by a doctor right away to assess your risk factors and be tested for heart disease. You are young, but 34-year-olds can have coronary artery disease. Best of luck to you.
