If the fever and sore throat doesn't resolve in 3-4ish days, see your physician. We have seen a lot of this since we are at the tail end of the flu season and some cases have also presented with sinusitis. May need to go on anti-biotics if this is the case, but most likely its a cold sooo just buck up, drink some OJ and sleep.
