Fluid in the inner ear?

Since around 2 months I had a crazy feeling in my right ear. Did not go to see a Doc coz I was out of country. Now I went a week ago and he dignosed Tinitus.
After taking medication for a week I had another appointment and he urgently recomendet to have a MRI done. Had that done today. Thanks God, no tumor or anythingelse to worry about.
Just some fluid in my inner ear.

I place this question, because my Doc is gone for next 2 weeks and my next appointment is the 25.

How does fluid get inside my ear? Can not have happened by taking a shower or wasching hair!
How to get it out?

Any ideas? Thanks in advance for answers

The middle ear ( i.e. the part of the ear where the small bones are, behind your eardrum) is lined with mucous membrane, like your mouth, nose and throat. All mucous membranes produce fluid. If it's in the ear, the negative pressure will cause the eustacian tube (the drainage tube from the middle ear space to the back of the throat) to collapse.
The best thing you can do is to take a decongestant (Dimetapp, Coricidin D).

theres a solution that i used when i was young for swimmers ear plus it will help the fluid crap in your ear its 1 part rubbing alchol and 2 parts proxside just put 2 drops in each ear move head side to side and so it goes all over the ear canal then dran with napkin or tissue it helps in healing and less irritation

I got fluid in my ear after an ear infection. The doctor told me it was behind my eardrum and that it would take months to clear up. My ears seem ok now except for some ringing sounds.
