Hello Doctor, My ears have been feeling very blocked/clogged for quite a while now and I could feel it especially when I swallow something, there is a clicking noise. There has also been ringing, especially after being in a loud place. Recently I've noticed a little lump behind my right ear, just under the earlobe. It's kind of hard and doesn't hurt. It's gotten a little bigger, a little smaller than a pea, though I'm thinking that might be because I poked at it. I also feel a little itching above it on my scalp today. Could it be an ear infection?
