Expected Duration

Trigeminal neuralgia is unpredictable. For unknown reasons, many people experience periods when the illness suddenly gets worse and causes repeated painful episodes over several days, weeks or months. This period may be followed by a pain-free interval that can last for months or years.

The type of treatment may influence how long your symptoms last. Some treatments carry a higher risk that the symptoms will return.
