Hi I'm wondering if you can get lab without prior virus or head injury? I've had vertigo for 9 weeks. Overall the dizzyness and foggy head feeling was subsiding gradually but when u think it's getting better it flares up again but this time no real foggy head feeling but dizziness and nausea seem worse! I have no deafness, or pain, just occasional clicking in left ear like something moving in there. Been doing brandt-darroff exercises and where you focus on an object while moving head daily for weeks. I'm at my wits end, does this sound like labyrinthitis? Will it ever go? It's been 9 weeks!! Thanks
