oh gosh yes a sinus thing would be a blessing.
you should mention T.N. to your neuro. at the least it will show that you have been researching on your own and that you are not clueless. it could be optical neuralgia or P.N. I pray it is not any type of neuralgia at all . yes let it be something simple and easy to fix!!!!! If you need to chat or anything you can private message me anytime. next time you go to your neuro have a written list of questions heck bring one when you go to that head and neck doc. too. write down things like when the pain comes and what it feels like or anything you notice that starts the pain, and include questions you have. that way if the doc dose not have time they can read it and get back to you and it will be in your file. and good to write it cus when you go to doctors you always forget the things you want to ask or mention.
I will keeping you in my prayers Catch.
Peace and Love
