I have had neuralgia now for quite a few years and had pain from lower jaw to top of head when I was given tegretol it was a relief but July this year it has come back but not from chin to top of head but from mouth to eye all on one side of face, my gp is very good and she has tried everything including taking max Tegretol per day to changing gradually to another medication starting with L but nothing working I have had a cat scan and she said nothing could be found I now have constant upper mouth and lip pain for 2 weeks and all I have is tegretol and panadein forte please help the panadein isnt helping much either
