I'm sorry, it's horrid isn't it. There are many other causes of facial pain, many easy to solve. Unfortunately, all these conditions are diagnosed on patient testimony, and if you have a useless doctor it's very difficult.

First thing to do is write a pain diary so the doctor can see that. He may want you to try an anticonvulsant or an antidepressant, but make him let you see a specialist if it goes on for more that a few months. Many people get TN attacks that then go into remission and some even don't have any more attacks.

Try not to stress about it as that makes it worse, easy to say I know, but even 10 deep breaths can make a difference.

Don't assume you have TN, I convinced myself I had appendicitis the other day, turned out I had a UTI!!

Best of luck
