Possible inner ear infection?

For a few months now, I have had slightly itchy ears, by this I mean right at the opening into the canal. I have several times now used a Q-Tip to just rub just that area, not sticking it into my ear, just rubbing the opening. However, since this has started and it has gotten progressively worse, my Q-Tip is coming out Greenish yellow with red swirls. I also have a lot of pressure in my ears, but it is allergy season so I'm used to having some. Then the last few days that I have tried to go out for my daily run, I end up nauseated in just a few minutes, and feel very dizzy. I can also feel fluid moving in my ears move. I'm 27 years old, and have never had an ear infection before, not even when I was a baby. So I'm not sure of how all of this is supposed to feel, or if it is just all part of my allergies.

Any help would be greatly appreciated. I have a doctors appointment for tomorrow, but now I'm just curious, because I have a headache, and am at work, and well like I said I just don't know much about ear infections.
