HI Jeff,
You are doing the best thing you can do, reaching out to educate yourself, I would suggest you try the cardiac forum but if you are not responding to blood pressure meds you should see a kidney doctor, sometimes artery blockage by the kidneys also cause high blood pressure that regular blood pressure meds dont work for, if you havnt seen a nephrologist yet you can ask your doctor to order an MRA of your kidney and bring that to your nephrologist, what kind of doctor is currently treating your blood pressure? I am on Normodyne, when my pressure was 160/100 my anxiety level was sky high, I felt like I am jumping out of my skin, how do you deal with that?
