Hi everyone...please help...i had to take a 40mg dose of prednisone for an ear infection and bronchitis....my feet swelled the next day...once i stop it..how long before the swelling goes down? I'm not urinating near as much and stopped the med.....according to the half life, it should have been out of my system but the ankles are still swollen.....please please help.....i gained 7 pounds of water from that one dose...is this typical?
