you should always seek attn to the er when this happens..you never know...get a EKG.and multiple blood work to show whats the problem..could be anxiety related or even gas Artus...but not with the left arm hurting....a heart attack can happen like this..or angina...always go to er..if have to call the squad..u never 2nd guess a heart pain never..
From your screen name and the fact that you mentioned your parents, I'm going to guess that you're fairly young. Heart attacks are not impossible in young people but not as likely. But pain is a signal that something is not right and you should be seen by a doctor. Hope you're feeling better by now and have some answers.
Anytime you have chest pain they tell you to call 911; however, chest pain is not a deffant sign of heart problems. I had chest pain, went to my doctor and they said I had Costalcondritis, put me on a NSAID and feel better now. With that said though you should go to see a Dr. ASAP incase in the off chance it is somthing serious. Also too anxiety attacks can cause symptoms like that try doing deep breaths and thinking positive.
