Last month I was in line at the pharmacy, and I decided to try out one of those automated blood pressure machines. I was surprised that the reading was a bit high, so I rechecked it on the other arm and got the same result. I decided to make an appointment with my doctor, and he told me that we would have to keep an eye on it and see what happened. I asked him what causes high blood pressure, and he explained it to me in a way that I could understand. I felt better after the visit, and we will be monitoring it closely for a few months.
