My Husband Had An Aortic Valve Replacement In January. He

my husband had an aortic valve replacement in January. He recently had a bladder infection and had a foley catheter. It was taken out on Wednesday after having had a urindynamic test. He was give a prescription for Cipro 500 mg for 3 days. Today his legs have become swollen. He isn't going to take the last pill tonight. Are the swollen legs a concern?
