Yes that number is high, Blood pressure measures the rate that blood pushes on your arterial walls. I would recommend that you monitor your blood pressure daily. A consistent high level will most likely have to be treated with meds.Some factors to consider are if you were frightened or stressed that day, if you just smoked a cigarette, had a high salt food for lunch, or if you have recently gained weight, as well as genetics could play a role in increased blood pressure. I would not play games with this, you can purchase an inexpensive cuff and stethoscope in a pharmacy or medical supply store or use a machine in the pharmacy to monitor. If you get frequent headaches or your ancles swell these may also be symptoms of high blood pressure.Becareful and please have my best wishes.
