Roof of my mouth turned white whenever i eat something it hurts?

Mouth pain: hello ~ this is either due to previous scald injury to roof of mouth from swallowing very hot, or even too spicey food (vindoo curry) or a viral or fungal infection of mouth ( herpes or coxsackie stomatatitis or candidiasis). In 1. cold fluid and food for 5 - 7 days, 2. see a doctor. 0.1% triamcinolone dental paste will help take pain away. thanks
