Well Hello ThisBe You have come to a GREAT site (neurotalk) that has some very caring understanding people.
The pains you describe sound like T.N.
I am not a Doctor so that is just my opinion . The best thing would be to find a Neuro and also a pain specialist and start on some of the meds that help treat T.N.
T.N. is caused by other things besides an injury . A blood vessel pressing on the nerve .. an infection that traveled to the nerve it may even be hereditary in some cases .
Try to eat easy chew foods . do things that help reduces stress . try warm compressions or others find ice pack helps.Try to learn what your triggers are. Read some of the stickies up above tips for new comers useful web sites and caring for one with T.N. are loaded with great info. most important I would tell you to Find a Neuro Doc and pain specialist.
Please keep posting because the best thing that sometimes helps the most more then anything else is being able to have contact with others who have this others who understand and know what it is like living with this.. Your not alone ! All of us here care and want to help anyway we can.
