Pain often refers to the temple, around the eye, and occasionally to the jaw and teeth.
It can cause headaches, facial pain, and tooth sensitivity, mimicking symptoms of migraines or temporomandibular joint (TMJ) dysfunction.

• Prevention Tips
• Practice stress-reduction techniques and manage tension in the jaw and facial muscles.
• Maintain good dental health and address any issues with teeth alignment or grinding.
• Avoid excessive chewing or jaw clenching, especially during stressful periods.
• Use proper posture and ergonomics to reduce strain on the head and neck muscles.
• Consider a nightguard or mouthguard to prevent teeth grinding during sleep.
