Hi there Patten, sorry your are dealing with pain... and also dealing with what doc to see or not see. So many many others have been on that road.
The best thing I think ,would be to go to the doctors or neuros. that are referred by your dentist and or your g.p. hopefully insurance will help in the cost of that . At least try to get referred to neuro. But myself I did find my oral doc to be of help in getting me in to see neuro. And yes wait on the meds. until a doc that knows can rx the right ones. And same goes for any teeth work make sure it is truely needed other wise .
I am sorry your are going threw such a tough part of the road right now and I wish you low pain and many blessings. I hope you see a great doc and find answers and control quickly. Glad you found your way here and yes it is a bummer it is over such pain. all the best. Keep us posted and let us know if we can help.
Peace
BMW
