so the teg. medication has helped? how long have you been dx with t.n. ?
how long has the pain been bothering you? do you see any pain management doctor? has this all come about over dentists and that led you to a neuro doc or why did you go to neuro to begin with because of the pain and symptoms??? I wouldnt want to jump onto neurotin till I have to .
You mentioned pressure causing pain then that I would say is a trigger ... hot ,cold.. triggers. do get the book striking back like jen suggested it is much helpful to you as well as any doc and dentists and family , friends... clues them in and a life saver of sorts. forget the root canal unless it shows on xray you need one... forget it!!!
sorry you are going threw what you are. keep us posted and hope to chat again soon with you.
peace earthwide
