38 year old male, 5'9" and 145 lbs. - Lately when I take my blood pressure, I notice large changes with each passing minute. For example, I sat down and two minutes later I took my blood pressure. It was 155/88 with a pulse of 87. I waited a minute, took it again, and it was 135/78 with a pulse of 78. I took it a third time and it was 124/78 with a pulse of 73. Should I be worried about high blood pressure? This has happened twice over the past two days. Should I sit longer before taking my initial bp? I do suffer from anxiety attacks, and this could also have something to do with it. Any advice would be greatly appreciated.
