Meniere's Disease Support Group
Meniere's disease is a balance disorder of the inner ear. The symptoms of Meniere's are variable; not all sufferers experience the same symptoms. However, "classic Meniere's" is considered to comprise the following four symptoms: Periodic episodes of rotary vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in one or both ears.
It's hard to say if you have Meniere's from just one very short vertigo episode. When I have vertigo it lasts for hours and returns several times a week. I think since you have had a sore throat for so long it could easily have another cause. It would be a good make an appointment with your doctor and let me check you over. I wish you well.
I will see my GP this week and ask for a referral to an ENT specializing in balance disorders, and pull4youd suggested. Thank you both so much for taking the time to reply :)
