Signs and symptoms[edit] Tension-type headache pain is often described as a constant pressure, as if the head were being squeezed in a vise. The pain is frequently present on both sides of the head at the same time. Tension-type headache pain is typically mild to moderate, but may be severe.
Symptoms usually subside within a few hours. Tension headaches are often associated with stress, fatigue or muscle strain. Activities that put the head and neck in a tense, prolonged posture. (i.e. reading, keyboarding, gum chewing or teeth grinding) can trigger tension headaches.
