Fluid in my ear *after* ear infection

Hi,

I've just recovered from "swimmer's ear, I was treated with Ofloxacin ear drops which I took for 7 days (today is day 8). 

Although I don't have any pain no more, I still have this weird feeling of having fluid running in my ear, from time to time.

Is that normal for now? Is it just the remains of the antibiotics? Is there a way to dry it up?

Thank you!
