Trigeminal neuralgia is the term used to describe sudden, brief, shocking or stabbing pain in the face. The trigeminal nerve goes to the forehead, eyes, jaws, cheeks and lips. Sometimes this very intense, sporadic pain occurs on just one side of the face. It can be caused by sinus or dental problems, injury, or TMJ disorders. It occurs in about 4% of systemic sclerosis (SSc or scleroderma) patients.
