Since it's so severe that it's closed off your hearing, anything you do yourself will not work and will likely make it worse. Putting in Debrox drops is a good idea to soften it for removal by a professional. For its actual removal you won't be able to flush it and shouldn't try to pick it out. You'll need to go to the doctor and have it professionally removed. They use water to flush and a metal instrument to scrape out what is left. It's actually a little bit of work they have to do even as a professional, so you're not going to get it out on your own even though it seems like you should be able to. I get this done every few years because I have a lot of build-up; several people in my family do as well. It's a fun time, really.
Once I had it removed and the doctor came in after the nurse cleaned me and said both ears were good. I went home and still felt full in one ear, and thought that it was water that was trapped. Still feeling full a few days later, I went back and was told the ear was still full of wax. So someone didn't know what they were looking at.
