How are the trigger points of Trigeminal Neuralgia form? And will they migrate to new positions?

Hello Anonymous and thanks for your post.

For those who are not familiar with this, trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head. According to the National Institutes of Health this is a form of neuropathic pain (pain associated with nerve injury or nerve lesion.) The typical or "classic" form of the disorder (called "Type 1" or TN1) causes extreme, sporadic, sudden burning or shock-like facial pain that lasts anywhere from a few seconds to as long as two minutes per episode.  These attacks can occur in quick succession, in volleys lasting as long as two hours.  The “atypical” form of the disorder (called "Type 2" or TN2), is characterized by constant aching, burning, stabbing pain of somewhat lower intensity than Type 1.  Both forms of pain may occur in the same person, sometimes at the same time. The intensity of pain can be physically and mentally incapacitating. Although the exact cause or triggers for   trigeminal neuralgia pain are  not fully understood, a blood vessel is often found compressing the nerve. For more specific information you can contact
