As everyone else says, see an ENT. If you google symptoms you will always worry yourself. Not every headache is a brain tumour! Medical diagnosis is done based on a wide range of factors that you will miss when you google specific symptoms. There's a reason the doctors get the big bucks.

What the internet can be useful for is helping you understand what the doctor tells you. The doctor only has a short time to explain what could be a quite involved medical condition. He also doesn't have time to explain the whole range of reasons he excluded a particular diagnosis, so again, don't second guess him with the internet.

I hope its a just a virus and gone soon.
