I got a virus infection in one ear years ago in Amsterdam. It provoked acute vertigo and I had to spend six weeks in England learning to walk again (between pubs for Guinness and a pork pie - what fun) before we could fly home. Bit wobbly thereafter, improved with special physiotherapy - and particularly by acupuncture. But after a major operation a few years later (14 years ago) I got permanent extreme vertigo and I've had it constantly ever since. At first acupuncture and physio helped, but as condition deteriorated I've tried everything else while it has steadily grown worse. As daughter's a specialist medico too I've had terrific attention including physical manipulation (only effective while problem primarily cochlea - the fishhook balance bubble in the ears). Variety of drugs supposedly help, but much depends on what's causing the symptoms. Spinal deterioration in neck etc seems critical with me now. Acupuncture no longer useful. Weekly physiotherapy helps free neck-bones and keep muscles relaxed (they go into cramp from constantly trying to balance head, which is heavy). Vital to keep muscle tone throughout body, walk, learn to balance with soles of feet and visually (I'm in outer space in the dark, and can't walk much now anyway). Lot of quack remedies and gizmos on market - I've tried some; avoid 'em! Vertigo can come and go, sometimes associated with tinnitus - but once constant, it's a black dog. I'd look for a top medical specialist in it. Curiously for years I lost the sensation of vertigo on my boat, as soon as the deck began to move over swells, but would be dizzy again in my bunk or on shore. But haven't been able to do that now for a few years - just when I finished rebuilding my last grand "little ship" at great expense! Good luck.
