Hi all
Just a personal observation about TN - like PN it can vary with individuals. Mine came on suddenly like a severe toothache but was later confirmed as TN. (I nearly had an unnecessary root canal or extraction but thanks to Bryanna on the dental forum I avoided that). My TN now is the least of my problems - it's still there but has moderated to being bearable. A lot of this I put down to the maintenance dose of steroids I'm on for autoimmune condition - that plus the massive dose of steroids I had while in hospital 6 mths ago which temporarily kicked it into touch. So TN does respond temporarily to steroids however you probably only want to go on steroids if you have no other options.

As madisongirl says it could be facial PN and given your other symptoms this would seem most likely.
