My roommate and I were fooling around and I got punched in the ear. The eardrum for sure did NOT break, because it would have been obvious, but my ear has been feeling "full" and clogged." There is no pain, it is just kind of annoying, but sometimes my hearing grows to this amazingly acute level as if I can feel sound. Weird huh?
You still could have an eardrum injury from the impact. It would be wise to have it checked, although waiting until next week is probably fine if you are not in pain.
