My BP was perfectly normal, 115-120/65-70, except at the MDs office. Then it spiked to as high as 180/95... But that man and his staff really
ticked me off at every visit. (For example, he refused to test my thyroid when I specifically asked him to.) When I go to my new
doc's office - and now that I'm on thyroid med - BP stays consistently in the normal range. No more spikes.
Most of the symptom lists I've seen say low BP is the usual thing with hypo; but realistically, it can go either way.
