I would take a guess that you don't have 'the flu' but a cold instead, you wouldn't be on here posting of you had the flu.

You can't cure it either way, you can only treat the symptoms to help make you feel better until it's gone.

Hot Drinks (I always have chicken soup)
Breathe in steam to clear your airways and help a sore throat
Rest
Gargle either crushed up paracetamol added to water or salt water for a sore/raw throat
Keep yourself well hydrated
