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.
Their cause is unknown but thought to be due to the contraction of the muscles covering the skull. Tension headaches usually occur because of physical or emotional stress placed on the body. Symptoms of a tension headache include pain which is described as âtightnessâ that begins in the back of the head and upper neck. It is usually mild in intensity, bilateral and not associated with vomiting or sensitivity to light. Usually, these headaches do not impair function.
