These are also some symptoms of mvps or mitral valve prolapse syndrome. You may want to have your doctor do specific tests to check for this. It is very common but often goes misdiagnosed for up to years because the symptoms can vary and can even subside for periods of time before flaring up again. Here a few web addresses to check for more info on mvp (you may want to check these first to see if you find similarities between your symptoms and those for mvp):

if ever you think your doctor is not fully answering your questions or "blowing you off" in any way, it's definitely time to see a new doctor at least to get a second opinion. Mvp can go undiagnoesed or misdiagnosed for years because symptoms can come and go and sometimes last only a few minutes and other times last for days. Some symptoms include fatigue, irritable bowel syndrome, chest pain, anxiety, migraine or other headaches, among many others. Check it out.
Good luck to you.
