A.

Maybe your right arm is healthier (just kidding). We are not equal on both sides of our body and a blood pressure test taken on one side can be very different than the other side. This is why it should be taken on BOTH arms to get a better average. Of course in your case, the left side is a normal blood pressure, and the right side said you are hypertensive. It would be best to get a several dozen more readings on a home blood pressure machine, at different times of the day, sitting/standing/lying down, and in both arms. Record all of those readings and report them to your medical provider.
