I am taking part in a medical research study and part of the physical was taking my blood pressure lying down 137/84. Then I had to stand for 3 minutes. it jumped to 1155/113. I have never been told I have high blood pressure, see my internist every 6 months and never had any heart issues. I also don't have any symptoms like dizziness, fainting. This was out of the blue. Of course I worried about it last night, so this morning I took my pressure with a wrist cuff before getting out of bed 123/85. Stood three minutes 155/115. Took it several other times same thing. Then I leaned on the counter and and took it again. It dropped to 138/100. I rested my arm shoulder height on the cabinet and took it again. Normal. What is up?
What was your pulse doing with standing versus lying down?
I believe your arm should not be hanging straight down when you take it standing, though it shouldn't necessarily have to be clear up at shoulder height. You might try resting the lower part of your arm on the kitchen counter (maybe use a thick book on top of the counter if it is down too far for your height) without leaning and see what happens?
Some people when they have orthostatic intolerance actually have a hyperadrenergic reaction to standing to prevent passing out, where the body overcompensates. I've had my blood pressure go up with standing with my P.O.T.S. (postural orthostatic tachycardia syndrome). My pulse also goes up.
Please remeasure lying down and standing, if you would, and list your pulses as well? I'm interested to know what your pulse is doing. You might even take your pulse just one minute after being in a standing position and let me know that number also?
By definition, if you have no symptoms, you can rule out POTS-hyperadrenergic or otherwise. What does your doctor say about your blood pressure? The information Living In Hope requested above would give a better picture of what might be going on. All wrist cuffs that i've seen instruct you to hold the arm to your chest during the reading, so having your arm in other positions will likely give inaccurate results. Read the instructions for your cuff carefully to obtain a correct reading.
