Are you sure it is trigeminal neuralgia? Why dont you consult someone in AIIMS or NIMHANS??
tell me, is here face physically affected also? is it like drooping or anything? because i have the same shooting nerve pain that starts from my face and goes to my neck! but my face is physically affected also, similar to bell's palsy. ive had it for like 4 years this pain. it healed a little for a while.
