Your blood pressure could be elevated for a number of reasons. It may have
just have been you were anxious or just an unusual circumstance. In order for
a blood vessel to burst in your brain, your blood pressure would have to be
extremely high or high for a long period of time. Your blood pressure is not
extremely high. In order to lower you can practice a few things. One is to
exercise, don't drink caffeine, cut back stress (fight or flight syndrome),
take omega 3's, magnesium, practice deep breathing, get enough sleep, maintain
proper weight, eat foods low in fat and higher in fiber, etc.
I would not panic over one reading like you had. High blood pressure is based on
measurements over a period of time.
