okay----I got to thinking about this, and I was thinking Oswald, Oswald, Oswald. Finally, I realized that LHO was identified in the 1981 exhumation of his remains partially by a hole in the mastoid bone in his skull, as indicated by his medical records. It's that hard spot behind your outer ear. So anyway----sometimes your inner ear develops an infection that is/was cured by an operation of that type. Anyway---symptoms are tinnitus, balance issues, headache, etc. So yeah---I would get it checked.
