Diagnosed with high blood pressure several years ago and been on a beta-blocker med to control it. That worked fine until a few months ago when my BP began to drop into the 90/50 range. I was advised to take my meds on an as needed basis. I can go for days with my BP fluctuating between 180/100 range then drop to the 90/ 50 range. When I experience this drop it is accompanied by dizziness and lightheaded feeling, with a noticeable pressure behind my ear drums. What can cause this erratic fluctuation? How can I be both hypertensive and Hypotensive?
