How Long Does Labyrinthitis Causing Vertigo, Headaches And Tingling Last?

I had a bad attackof vertigo 4 days ago and couldn t even sit up. I am still unsteady on my feet if I get up too quick. I did have difficulty reading amd had headaches throughout (I do suffer from Migraines). I also have pins and needles in my right hand. My GP said I have labyrinthitis as I had influenze 2 weeks ago, how long does this last?
