Jim -- buy a home blood pressure monitoring kit and keep a record. I had always been told I had high blood pressure, but turned out to be white coat syndrome.

Last few years I was told "you have low blood pressure" then "you have high blood pressure". Sheesh... just seems my BP likes to vary all over the place. Sis was visiting, retired Hospice RN, and with me post lung biopsy. Sure enough sitting there she got to watch it drop to 80/50 then climb up to 160/100... then back down. When medications are "on" I am pretty steady at 110/70 these days... but it likes wondering around. When low, I get dizzy and have to use caution when standing up. These days I just want the medical folks "do not medicate for BP" fun times.
