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 not associated with nausea or vomiting, and do not have symptoms like flashing lights, blind spots, or numbness or weakness of the arms or legs which precede the headache. These symptoms can help distinguish tension headaches from other types of headaches (for example, migraine headaches).
