Heart palpatations are a symptom of fibro but when I developed them I headed for the doctor. He did an EKG, echocardiogram, and ultrasound of my heart and carotid arteries, and had me wear the monitor for 24 hours. My heart was fine and I now was relieved. I wasn't going to take chances. My husband saw his doctor regularly but still died from a sudden heart attack. We just can't blame fibro for everything.
Shortness of breath can also be a symptom of anemia and of diabetes! If your doctor ignores your symptoms, you need to find another doctor. They are not doing the job that YOU hired them to do. You are paying them for their services. If you got no food in a restaurant, you'd get up and leave, wouldn't you? There are good doctors and bad doctors and you want the good ones. After all, they get paid plenty to help you.
