For the last 3 months or so ive been really stressed out and Im 18 years old. Yesterday after running in gym class I noticed a pain sort of underneath my right breast and it kind of came and went and then I slept and today i woke up and didnt really feel the pain and then i stared to feel it later in the day and im on my schools poms squad and I started to feel it more there and right now Im at home and it just feels like a discomfort in my chest. The last time I was medically checked out was when I went to the doctors on January 10 and that was for pelvic pain and there they did a blood test and a CT scan so I don t think my heart is in any bad condition. My mom wont take me to the hospital because she thinks it is all stress. Am I having a heart attack? I am so scared right now. in my family we have no heart attack history Im scared because Ive had it for all of today. Im really scared
