I think I have water in my left ear, and I've tried almost eveything to get it out, any suggestions?

Probably not water . Please see a doctor. There are so many times patients come feeling as if they have "water in their ear" whose ears are fine on exam. Hearing loss, ear pressure, TMJ can all cause this feeling.
Try this. First off, it'd be nice to know if you indeed have water in your left ear or not. Sometimes, that's what people think but often it turns out to be something else. You may have tried this, but i will still try to fly a kite in case you might have not tried this. You want to do valsalva maneuver in that you want to take a breath, hold it, clip your nostrils with you hand and strain as if having a bm.
