23, female A few times in my life I either stretched/took a deep inhale and it caused my chest to seriously hurt right under my lt breast. This has happened 2x, the last time was the first moment that I felt my heart actually throb in my chest. pain went away just a few moments later each time. I am a general ultrasound student, I had a echo student scan me one day and she vis. a small flicker between my ventricles during diastole which the instructors confirmed was a very small defect. and common. I haven t looked into this being a broke student and all but could this be the cause of my symptoms noted earlier? Are their certain things I could be doing to avoid the episodes? Should I see a doctor asap or can this wait til later on in life?
