I saw the nephrologist today. Apparently my kidneys are ok despite an abnormal test, but the results of the 24 hour blood pressure test say my blood pressure is consistently in the 140s and sometimes 150's (the top number at least) even when I'm sleeping. So I started on blood pressure meds today. I was considering asking if I could go on a beta blocker because I've read those work on anxiety too, but I decided to let the doctor do his work.
