Tension headache is a primary form of headache that is characterized by episodes of widespread pain throughout the head, of mild to moderate intensity, that does not worsen with physical activity, and that occurs without or with limited accompanying symptoms.
Tension headache is the most common form of headache in people of all ages and can occur episodically, in relation to extemporaneous and time-constrained situations, clinical conditions, behaviors, or psychoemotional states, or recurrently or constantly, taking on a chronic course and being more or less debilitating in relation to the intensity and duration of the pain.
