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.
Tension headaches are considered a type of primary headache, which means that they are not caused by another medical condition or disorder. Other names for tension headaches include muscle contraction headache, ordinary headache, psycho-myogenic headache, and stress headache.
