hello and welcome to neuro talk. Sorry you are here for t.n. but glad you found us.
I dont have issues with my b.p. mine is always on the very low side.
but when it comes to weather and pressure changes that totally affects me and the pain...also when I bend down and the blood flows different then it affects me.

I would suggest you try and find a neuro doctor ..they should be able to answer some questions and know if you have t.n.
I know many people who have sought dental work hoping that would fix things but in reality it was not a dental problem and made things worse. so I would see a neuro you should be able to be referred to one by your general doctor. So far to me and I am not a doctor by any means...but you do describe side affects of t.n. they are many meds that help controll this you just need to find the right one or the right combo .
Please know we are here and will help as much as we can.
sending low pain to you and keeping you in my thoughts and prayers for you to find answers and relief soon. let us know how things are going and how things turn out.\
PEACE
BMW
