I have been feeling super short of breath lately, a lot of air hunger. I went to my dr he ran blood work and everything was fine. My BP has been wonky, i have a cuff at home and it reads 100/85 ., 95/74, 102/83 ...which indicates a low pulse pressure, every single time I take it..my pulse pressure, which is the two numbers subtracted, is low. It is supposed to be 40. I am wondering if my birth control pills could be causing the bottom number to be higher or if I am in heart failure and that is why I am having such shortness of breath. I go back to the drs next week, and I am just a disaster. Does anything know anything about this pulse pressure?? SHould I go to the ER?
