Suggest Treatment For Blocked Ear

I just read a discussion post about ear infections and I think I have one. The past couple of days I have had intermittent dull throbbing discomfort in my right ear and yesterday I was relaxing and felt like my ear was itchy or as if something was in it. Got some tissue and there was a little glob of clear, light brownish discharge and it had a slight smell. It immediately felt better but then today it's been feeling more and more heavy or blocked. I remember my mother putting mineral oil in my ear many years ago when I had an earache, would that help if I did it tonight?
