How is trigeminal neuralgia diagnosed?
As with many similar conditions, much of the diagnosis of trigeminal neuralgia is based on eliminating all other conditions first:
“There is no single test to diagnose TN. It can be hard to diagnose, since many other conditions can cause facial pain.”
Doctors will conduct a thorough physical and neurological exam. Patient history will include location and incidence of symptoms and any potential underlying conditions that may have caused the condition. Post-herpetic neuralgia (nerve pain caused by shingles), cluster headaches, and temporomandibular joint disorder (TMJ) have similar symptoms and patterns and will be eliminated as possibilities first.
