My BP pressure has slowly creeped up over the years to 155/95 range, despite being quite fit with no real lifestyle issues. Was told to monitor it. Did a reading a few weeks ago: 190 over something. Not good. Went to A&E where they confirmed the reading with their cuff. Sat there for several hours. BP kept climbing until it reached something like 235 over something (probably partly due from a feedback effect of knowing my BP was high). Felt fine, apart from the anxiety related to the BP reading. Did a few tests, but no-one seems to know why it spiked. They gave me some meds and it slowly dropped. They let me go when it dropped below 180. Now taking a calcium channel blocker and it is very slowly trending down. Now about 160 over 100.
