I have been suffering from vertigo and oscillopsia for over 20 years after a head injury. The more active I am, the more symptomatic I am. Any action that requires any moderate head movements/jerks, especially gardening and car rides worsen my symptom. Sleeping on left side also worsen the symptom. I have been through multiple ENT/Neurotologists and no one has come up with any diagnosis. My symptoms disappeared for two weeks when I stopped doing any chores that required head jerks (including cooking and car rides). One of the expert neurologist suggested that I have left vestibular nerve compression, I do have 25% left vestibular loss (only on balance). In fact I have no auditory loss. Any thoughts?
