Hello, I've Been Feeling A 'full' Feeling In My Right

Hello,

I've been feeling a 'full' feeling in my right ear for six days now. When the pressure becomes heavy I become dizzy. I've tried hydrogen peroxide, decongestants and even began a course of amoxicillin as I have them on hand for dental procedures and am currently without medical insurance. Nothing has made a difference. No other symptoms. What can I do?
