Go to your local grocery store and stock up on ginger ale and juice (something smoother, less citric acid like apple juice) also pick up some Cepacol Lozenges (they contain benzocaine, a local anesthetic that numbs the raw areas of your throat). Drink plenty of fluids and rest, its probably just a short term cold. If it persists, it could be allergies or something more severe like strep. Make sure to see your doctor if it lasts for more than just a few days.
