I'm plagued with ear infections in my right ear. I get them 3 ~ 4 times a year and recently in my left ear.
They had to put in a T-tube to drain it and they gave me ear drops with steroids. A T-Tube is a semi-permanent tube that has little clips on it that hook on the eardrum on the inside that keep it from falling out.
Those steroids can be nasty though. When I hear something I don't like, my ear drum punches me in the brain and knocks me out.
But seriously folks ...
Good luck at the ENT Spec. Ear infections suck ... hope you get it cleared up soon. I couldn't imagine putting up with one for a month. :(
