Viral labyrinthitis--Sudden onset vertigo with plugged ear, some hearing loss and tinnitis. Nausea and vomiting may be present with the vertigo initially. After a few days the whirling downsizes to dizziness with everything in the surroundings appearing to sway and bob as you move about. Most websites say that all the symptoms disappear in 4-6 weeks but there are execeptions. Mine has continued unabated for over 3 months. Other than exercises to retrain the brain for balance, two ENT's say there is nothing else to be done. The dizziness should eventually disappear with the balance therapy but the plugged ear (particularly obtrusive and pronounced) and tinnitis could be lifelong.
