I am a 16-year old female. 4 years ago I went to a doctor and found out that I am suffering from a respiratory tract difficulty (plus pneumonia) and told me to take some meds. 2 years later, I felt spontaneous chest pains every now and then. Then I tried consulting the doctor again and said that there is nothing wrong. I told the doctor that I used to drink 2-3 bottles of soda everyday, and concluded that maybe I had heartburn. That's why she suggested that I should take an ECG test. But I couldn't find any place where they conduct such tests because of the fact that I live in a province. Since then, I ignored these chest pains. But now, I think they became worse. I lessened my intake of soda to twice or thrice a week now. Is there any connection with my past health problems?
And one more thing, there's this one time when we had a PE activity wherein a fit/normal person's heartbeat per minute is 30-40 but then I was the only one who had a high set of heartbeat of up to 70.
