I have been living with trigeminal neuralgia since 2004 when it was first diagnosed. I am taking carbamazepine, occasional lamotrigine and have recently been advised by my neurologist to add pregabalin, 2 daily. At present, my TN has shifted from the usual position from the left side of my face and down the left side of my nose to a new and very painful path from the scalp (front forehead) and down the left side of my nose. I cannot bear to touch my scalp without bringing on a spasm. Is it normal for trigeminal neuralgia to change position in this way? Thank you.
