Yeah I've been having pain with my wisdom teeth atm, they suck. Make appointment for dentist asap, do the painkillers as stated above, and gargle salty water. Quick tip though: if you need short term, very effective relief, a tiny bit of hard alcohol, soaked on a piece of cotton wool and held over the sore area will locally numb it for a bit, if it's proving too distracting to do something. A warning though: don't do that directly after or near painkillers, as although you won't be swallowing much alcohol, they can react badly. Of course YMMV- this works for me.
