question: Hi, I have had elevated to high BP for year. I stopped taking my meds few months ago as I am working out with trainer 2-3 week. Recently feeling light headed, dizzy, almost fainted and chest tightening. (same symptoms as I felt when I found out it was elevated) I went to DR just to get blood test & my bottom # was 90 top think 136 or 146. So I knew I had to get back on the meds. Waiting to get blood test results. My ? is how do I know I am not experiencing something worse?
