Don't frighten the guy by saying it's a medical emergency, but obviously best to see the doc. First time I had labyrinthitis I was terrified and went to the doc. She listened to my symptoms and said, "You'll be OK. It's inner ear infection which will probably go quite quickly". It did - coupla days and I was fine.
I have since had it about a half-dozen times in 40 years, often associated with a cold or sore throat. Never taken medication.
Hope it clears up soon....
