Sounds like an inefection which my sister has just been diagnosed with. She ahd the same pain as you and went to the dentist and has an infection in her gum (where her wisdom tooth is coming through), spread to her jaw and her tongue (?? didn't know you could get infectio in your gum!!) Anyway, until you can get to the doctors / dentist try Paracetamol & Codeine along with Ibuprofen (as long as u r not sensitive to ibuprofen, asthmatic, history of stomach ulcers etc) The combination of painkillers should HOPEFULLY get you through the worst until you can see someone. I'll be thinking of you as I know how much pain my sisters been in - horrible x x
