Dear Closet Monster. I have had the same symptoms. I am lucky as my primary care provider believes my report of symptoms. He has ordered meds (metropopolol) and a statin. And he keeps referring me and testing me though results come back normal except for tachycardia. I am now on CPAP as my oxygen level falls at night while I am asleep causing my heart to beat too fast. I have now been referred to a cardiologist and a pulmonologist. I am lucky that my doc is willing to believe that I am just "not right" -- shortness of breath and what I call a "fuzzy head". Good luck in finding a doctor who will listen.
