My blood pressures varies between my right and left arm and also fluctuates significantly sometimes. Just checked it on both arms, my left arm was 134/78 and my right arm was 155/98. Is this a sign of blockage on my left side? Also, the fluctuating blood pressure concerns me as well. I'll sit down, relax for about 15 seconds and take my first reading. It is always higher by approximately 10 points, usually around 145/85 or so. After I wait about a minute and take it again, it drops to approximately 130/75. I can replicate this consistently by walking around for a minute and starting the process over again. This can also be replicated in each arm as well. I am a 35 yo male, 5"10 202 lbs and have been diagnosed with stage one hypertension. I have changed my diet and have begun to take myself off of my blood pressure meds but have always checked my BP on my left arm which is my dominant arm and has always fallen within normal limits, at least what the doctor called normal for me while I am on meds. I recently started checking my left arm and have noticed this huge difference and it is fairly consistent. 10-15 sometimes more.
