Sounds like you suffer from something that I and many others have - White Coat Syndrome - and I can send the BP machine through the roof. AMEs are usually aware of this problem and will try to relax you and take several readings. On my penultimate medical before retirement my BP wouldn't come down so the doc fitted me with a 24hr BP device. Next day when he put the results in his computer it was 100% normal. Don't worry - I know it's difficult but that is the real problem.
