Sometimes i get a sharp pain in my heart. it comes and goes. sometimes my left arm feels wired, could it be my anxiety or should i get checked?

Probably anxiety: If you have a sharp pain in your chest area and last second or so it is not angina. By definition angina is a pressure type chest psin that last 5 to 10 min occurs with exertion and improves at rest of nitroglycerin. Sometimes rediates to the jaw and arm. Given you age and atypical nature it is unikely that this is heart. Nontheless i advise you to see your doctor for a check-up.

Yes: Although you are a low risk cardiac patient , the symptons you are having are bothering you. Even if its anxiety , if its causing issues it needs to be addressed . See your dr
