Hi, I m a 34 year old female. My heart rate has been high lately, and I often feel slight pain in my left side around my breast area. I ve been to two heart Doctors and wore a monitor for two weeks. Everything came back ok. A few times on the monitor my heart rate got a little high, and at the second doctors office my heart started racing, and it was a little high. The doctors did say to lose weight and stop drinking caffeine. But, I m SO scared and I feel like something is going to happen to me. The heart doctor at the University Of Penn, said there is a pill to lower the heart rate, but I should try losing weight first. When this happens its a REALLY uncomfortable and scary feeling, it s happens when I m totally relaxed or even ready for bed.... Can anyone tell me what they think about this. Thank you :)
