Random glad you found us but sorry about the pain your having. It sounds like T.N. to me also.
How do you sleep at night? do you lie flat or..like me sleep in a happy recline chair?
I think the position of head changes the blood flow and may be reason for issues at night trying to sleep. I can not lay on one side of my face or have anything pressing on it...
The best thing to do is see a neuro ...I see you mentioned it may be a bit of time before that happens so I am hoping it happens sooner then planned. Do NOT have any teeth work done unless it is shown to be a necessity. Also take the meds your doctor gives you and let your body adjust and the meds to get into your system . Many of us T.N. folks have to switch and combine meds before we find what works best for us. Everyone is different.
You think it odd you dont show or present Typical symptoms of T.N. yet to me your story / info sounds like many other T.N. people I have been in contact with over the years .


I hope all of US keep you from ever....

Low pain and good sleeping. . .

Oh have you tried a heating pad on that area sometimes warming the area helps calm the nerve down. maybe try sleeping with head in more of up right position.

Keep us posted on how you are doing and let us know when you get apt with neruo doc.
PEACE
