I do suffer from high blood pressure and high cholesterol and take meds for both. I also have heart palpitations which sometimes cause me to cough. I try to use the "process of elimination" with the doctors and am considering seeing a cardiologist just to rule out any cardiac issues, then maybe a gastroenterologist to rule out any gastro issues. The only problem with this process is they all run various tests and my insurance doesn't cover everything so it can get expensive. It seems like my primary care physician has run out of ideas.Maybe I'll just have to continue living with it.
