Anyone else experience periods of heart-racing/light-headedness? I've had a couple bouts of it today while sitting still... no big exercise, not even walking up a flight of stairs before it happened. I kind of had a feeling in my chest similar to an adrenaline rush when your nervous about going on stage or starting a race -- rapid heart and kind of tightening -- then felt very faint, and got very warm and broke out in a sweat. All symptoms went away after a few minutes of putting my head down and breathing deeply.
I have vague memories of having similar feelings during my first pregnancy -- but that was 12 years ago (OMG - I'm getting old!) -- and I can't recall if it's relatively normal, or something I should call the doc about.
Thanks in advance for any insights. ~M
