I've got a pretty long medical history with congenital heart disease, two open-heart surgeries, and a pacemaker implanted because of atrial fibrillation. My thyroid levels are low, and I'm on medications like Cordarone and beta blockers. It's been rough over the last year with this intense pounding sensation over my nose and super high blood pressure that just won't get under control. I've tried all the check-ups I can think of. What could possibly be causing this uncontrollable high blood pressure, and what can I do about it?

Uncontrollable high blood pressure can be challenging to manage, especially with your complex medical history. Since you are already on Cordarone, a Beta Blocker, and thyroid medication, one option to consider adding is an ACE inhibitor like Lisinopril. The recommended dosage for Lisinopril is usually starting at 10 mg once a day, which can be adjusted based on your blood pressure response. Additionally, a diuretic such as Hydrochlorothiazide may also be beneficial in controlling your blood pressure. It is important to monitor your blood pressure regularly and work closely with your healthcare provider to adjust your medications as needed.
