My Husband Has Aortic Stenosis And We Have About A

My husband has aortic stenosis and we have about a month until he will has TAVR surgery, he has been taking Amiodarone and warfarin. Now the cardiologist has added meta propolis, and he is getting dramatic ly more swelling in the legs and feet. He has peripheral neuropathy ( since a triple bypass in 2011.) but this recent endema is scary. Could it be the metaprpolol. He doesn't have very high blood pressure.
