If the sore throat is from a virus, there are several at home "remedies" you can try - they won't "cure" the virus that is causing the sore throat, but will make the throat feel better so you're not so miserable - hot tea with honey or lemon (or both), gargling with warm salt water, popsicles. Stick with easy to swallow foods such as applesauce, scrambled eggs, jello - avoid spicy or highly acidic foods.
