@unmanageable I'm wondering what you mean by unmanageable? What kind of numbers are you getting? You can always get a second opinion too.
I unfortunately have "labile hypertension" so my readings can spike high & low, thanks to a cancer drug that caused it. But the 3 meds I'm on do a pretty good job of keeping it controlled and me out of the ER. A really good doctor is worth a lot. The best one for me has not been a cardiologist, but a Nephrologist. Hope you find help.
