I have been having uncontrollable high blood pressure, rash, fatigue, swelling, nausea, chills and a metal taste in my mouth for the past 4-5 months. My heart doctor has changed my bp meds five times and its not as high but not good either. However, the meds have made the swelling worse. I was diagnosed with a 70% blockage in my left renal artery......what is your recommendation??
