Thanks, Sushi, Valentijn and SOC. I'm profoundly confused about how to proceed from here. It sounds like specialists in this are rare, and I just don't want to go to yet another doctor who knows less than I do (which isn't much!). EDIT: There are 2 specialists within an hour of me, and neither is seeing new patients for 6 months. I had taken 1/4 tab of florinef and about 1/4tsp of sea salt for 3 days, including the day of the tests. I've stopped both today, and I'll redo the test in maybe 3 days (does that sound like a good wait period?). I'll also redo the standing still test, with BP at the end. It does look like the florinef + salt has moved me from lifelong low-normal blood pressure into the high range.
