The answer you might want to hear: Ibuprofen would make you feel better than you are. Two pills constitutes an adult dose, four is equivalent to prescription levels. Drink lots and lots of fluids, and don't make the ibuprofen a habit.
Too much regular use of the stuff affects your platelets and therefore your bodies ability to heal its self.
The answer you don't want: Nothing will make it better other than lots and lots of bed rest, going out and being active will probably just make it linger for longer (and quite possibly get worse).
