Hi ray, I also have differences between my arms. I have BAV (Bicuspid Aortic Valve). Which means I have one less valve on my heart than most people, but it's also the most common birth defect.

If you have something similar or even an arm injury it could explain the difference . The big question is how you feel. As long as I take my BP med and watch my diet I feel good, as soon as I don't I feel awful.

Hope this helps.

Hugs, Phoebe :-)

i feel fine but i also have afib so i am also on blood thinners. then i am also prediabetic , i guess hits just keep on coming .

thanks for replying

My right arm is almost always higher than the left.
But I take my BP 2 times in a row. The same arm, a minuet apart my systolic pressure is almost always different, sometimes 20%. My doctor says it is most often the margin of error of the machine and the systolic reading is the easiest to miss. Not to dismiss any other problem, let your doctor know of this.

My cardiac doc takes pressure in both arms then records the average. Now, I cannot record left side because I had mastectomy on that side. Just a thought.

I've always been told to take pressure with the left arm. So I'll have to try the right arm and see if I get similar reports like others have gotten.
