high blood pressure
"I've been on Norvasc for about 15 years after after being tried on almost every blood pressure medication.  It has been the only medication successful at keeping my blood pressure in normal range.  In January of 2009 I was hospitalized in a thyroid storm.  A thyroid storm affects every system in your body and you feel like you are near death.  I was placed on Bystolic to control my heart rate 120 -200 bpm, palpitations and shortness of breath.  I could only tolerate 5mg due to severe drops in my pulse rate 40 - 42 bpm.  I stayed on Bystolic and Norvasc until February of 2010.  I was then instructed to slowly taper off the Bystolic since the thyroid condition was resolved.  I was unsuccessful in tapering off Bystolic without arrhythmias."
