Hello, I am a 44 year old female with a history of palpitations. For the last month I have been having kind of a flip flop in three places - the base of my throat , the top of my left breast and the bottom of my left breast. These have been not been like my normal palpitations which I normally cough and that seems to correct it. Not sure if this is related but for the past week . . . while eating I seem to have a slight discomfort in my upper abdomen . Thanks
