  • Cluster headaches
    
    
  • Local disease in the sinuses, jaw, throat, and bones of your head
  
  
• Physical examination of the head will help define other possible causes of this painful syndrome. Physical findings in people with trigeminal neuralgia are normal.
  
  
• A doctor should complete an initial neurological examination to determine the presence of other conditions, such as multiple sclerosis, that are associated with nerve pain syndromes like trigeminal neuralgia.
