I am currently in a state of bamboozlement (if this is even a word) about apparent differences in my blood pressure readings between left and right arms. Sometimes for example it will be 135/80 on the left side and 147/90 on the right side or 120/80 on the right and 125/92 on the left. I have read on another website that this could be caused by an obstruction in the subclavian artery branching to either arm, but if so wouldn't it be more consistent and polarized on one side. And this has only occurred within the past year or so. Is it likely that the elevation could be caused by my being anxious about taking it in that arm? I tried with automatic machines that test either upper or lower arms and the numbers were similar between upper and lower on a particular side. Any ideas?
