I've had these on and off for a number of years, been to the GP with it, no answers there, they've been fairly rare/mild recently - until last night when I had a really bad episode. At its worst it's:
begins with tingling/itchy palms
heart rate begins to ramp up
shallow breathing
nausea
really hot - especially head/face
heart beating really fast
...then after a few minutes all calms down, goes away and I'm back to relative normality within about 10-15 mins. Last night was bad though - I felt like I was about to pass out and felt so nauseous I did actually throw up. Then afterwards my heart rate was super-fast and felt very irregular. I still think it's a bit high (resting heart rate 90+)
Can occur at any time of day but most often in the evening or during the night - I wake up and feel the weirdness coming on.
What is this?? Does anyone else have similar episodes? FWIW I am 40, and pretty healthy generally. I have had Graves Disease/hyperthyroidism about 13 years ago and although I suspect some perimenopausal symptoms, have been tested for hormone levels and thyroid and all seems to come back within normal range. Last test was maybe early this year after a few irregular periods. I've also had an ECG check for palpatations, which I also experience fairly regularly, and wore a heart monitor for a week - again, nothing out of the ordinary discovered!
I sort of want to go back to the GP after this last one as it was quite sudden and severe but I'm going to feel like a fraud again if any tests come back normal... At the same time, I can't help feeling like there must be something 'wrong' - otherwise I wouldn't have these funny turns! What should I do?
