Suggest Remedy For Sore Throat

I fell, literally on my face Saturday. I immediately put a cold compress on it. (Right below my right eye) There is no bruising and didn't even damage my glasses but Sunday morning I awoke to what I thought was a sore throat. The very back of my mouth (palate) is still very sore. I've been taking ibupropin and learned not to eat solid foods. My guess is that the injury pushed all the way back to my soft palate. Am I right and how long does recovery take?
