The only thing people haven't mentioned among rest (frustrating but essential), ice (drippy but the most effective), taping (really reduces collateral damage from when you have to walk to the bathroom), and propping it up (this reduces the time that you have to put up with the rest!) is taking Advil/ibuprofen or aspirin (not Tylenol/acetaminophen; it's not so helpful) to clear the swelling and bruising.
