Sore Throat

I am having sore throat now. I have no idea what's wrong with my health. I already drink a lot of water and also control to consume those fried or spicy food. But, wh I am still have to suffer sore throat now? I though everything will be ok if I do not eat any fried or spicy food. But I am wrong. sob

I am feeling want to back home and have a good sleep now. So tire and so bore to stay in office with not managet to say a word.
