Sore throat seeming to originate from sinus page to throat?

To sooth your throat and help with congestion, try a vinegar or lime mixed with honey (vinegar/lime will attack any infection and honey will coat your throat) you can add a bit of tea and or brandy to help you sleep), but this will not help a sinus infection. The dripping behind your throat could well be coming from your sinuses and even ear infection. You may or may not have pain behind and under your eyes. Not to be gross, but when you blow and/or cough up stuff if it is turning color (yellow or green) then yes you have a sinus infection. You need to see a doctor before it gets worse and if not treated it will get worse. For pain try motrin.
