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 dull pain, tightness, or pressure around your forehead or the back of your head and neck. Some people say it feels like a clamp squeezing the skull. Often called stress headaches, theyâre the most common type for adults. When you get them less than 15 days per month, theyâre called episodic tension headaches. If they happen more often, theyâre called chronic. These headaches can last from 30 minutes to a few days.
