I'm wondering if anyone else has blood pressure issues.

My blood pressure has been all over the place for the last several months. Last week my primary care (family doctor) decided to put me on a water pill trying to get it stabilized.

I ended up in the ER (directed to go by my doctor) with my heart racing like it was going to jump out of my chest. My pulse at rest was 128 and my BP was 158/111. The hospital diagnosed low potassium 2.0. Some how in less than 5 days it dropped from over 5.0 to 2.0

She took me off the water pill and now I am on metroplol. Only 2 doses so far. I'm monitoring my BP and pulse at home. I'm having an ultrasound on my heart next week.

I'm wondering if this is common with RSD and what others experience has been getting it under control.
