"Ear disorder...characterized by inflammation...which causes dizziness." (major symptom lately)
"Occurs following an upper respiratory infection." (I had a nasty one for a month prior to recent dizziness and breathing fun.)
"Symptoms....abnormal sensation of movement, loss of balance....may be severe...severe episodes may be followed by transient episodes." (Check, check, and check.)
The diagnosis? Labyrinthitis.
I kid you not.
(Those of you who know me or have seen my web page will understand the giggling.)
