Hello, being taking Fluclocaxiillin prescribed for an ear infection. Ear infection not getting better and this is today is the 6th day of a 7 day course. The problem I am having now is that I have painless swelling around my ankles(like fluid build up), my calf and thighs are kkind of tight, and my stomach feels bloated. What can possibly be the cause of these? I am a bit worried.
