BB could your sudden rise in BP be a case of "White Coat Syndrome?" I've never had high BP but a few years ago whilst going through the menopause, my doctor suggested I had an internal examination. He then decided to check my BP first..... surprise, surprise, I had high BP!
I monitored it for a week and it was perfectly normal. Went to the BP clinic and had it checked again, all good. Told the nurse about my visit to the doctor and she rolled her eyes and muttered something to the effect that she wished (male) doctors would engage brain before taking a BP reading.
