R.I.C.E.
Rest
Ice
Compression
Elevation
Ice should be done 10-15 min on then 10-15 off. You could throw some NSAIDs in there as well if you want..i.e. ibuprofen, tylenol, naproxen etc. If you compress it (wrap) do not sleep with it wrapped. You could bengay it if you want, but that's used usually more for sore muscles, which this does not sound like. Either way, it won't hurt anything.
