Trigeminal neuralgia is primarily characterized by sudden, severe, electric shock-like pain attacks, often described as stabbing or throbbing, typically affecting one side of the face. These excruciating episodes, lasting from a few seconds to minutes, can be spontaneously triggered or provoked by various stimuli such as light touch, chewing, talking, brushing teeth, eating, shaving, applying makeup, or even a light breeze. The pain commonly radiates to the jaw, nose, and cheek, though in some cases it may extend across the entire face. Associated symptoms can include stinging, burning, aching, facial spasms, or tingling and numbness in the affected area. The frequency of these pain attacks is highly variable, ranging from multiple episodes within minutes to prolonged pain-free periods lasting days.
