My tounge is sore and bruised and i got a singing compitition 2morow pls help!!!!!?

I am a singer as well. First don't talk under any cirstances. You need to see a doctor and get some antibiotics it sounds like you have a virus. There is no natural remedy for this. Maybe some warm salt water gargled and held in the mouth. Do not eat anything except soup and drink water to replenish fluids. Get into bed and stay there until you have to sing. The adrenaline rush will give you the voice to sing tommorrow and you'll get through it, but you need to go to the doctor. Chookas.
