When I measure my blood pressure at home, one arm often gives a higher reading than the other. The difference isn’t always identical, which makes me unsure whether it’s a measurement issue or something worth mentioning at my next appointment.
How much variation between arms is common, and what’s the best way to compare them fairly? I’m using the same cuff and measuring both arms within a few minutes, but I may be missing a detail about posture or timing.
