How long for? Meniere's disease usually is a combination of vertigo tinnitus and deafness .You may have labyrinthitis (vestibular neuronitis) nausea and vomiting often accompany vertigo regardless of the cause see an ENT specialist.
Meniere's. Your symptoms sound very much like meniere's. I would suggest seeing an ear nose and throat specialist for specialized hearing and middle ear testing. Here is a link to reliable detailed information about meniere's: http://www.Nidcd.Nih.Gov/health/balance/pages/meniere.Aspx.
