I have experience heart palpitations, like a flip flopping sensation, for the past 2 years. It was infrequent, however recently I have had this sensation several times a day, often when I have had no caffeine. I have also starting noticing a pulling sensation in my left eyelid, and a pulsing sensation on my scalp. None of these things are painful, just rather disconcerting as they have become much more frequent. Anyone have any suggestions? I do have an appointment with my doctor in a couple of weeks. %-)
