When I was around 6 years old I had a bad ear wax build up like that. Of course, I don't remember much about what my parents tried (I obviously couldn't take care of it myself), but I can tell you what ended up getting it out. We finally had to go to the doctor, and they used one of those squeezy blue things (i've never known the name but they come with some ear drops at the store) I think they filled it with water, made me hold my ear over a tub thing, and squirted the water into my ear several times. It finally came out. I'm sure they softened it up with something, and I hear that baby oil, peroxide, or just normal ear wax removal drops will do that. I hope you get it out, because I know its not fun.
Oh and I wouldn't suggest using q-tips right now, or anytime because they do push wax further back and would probably make it worse.
