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.
The most common types of headache are migraines and tension headaches. Other types of headaches include cluster and rebound headaches. Most people describe a tension headache as a constant, dull, achy feeling on both sides of the head, or like a band around the head. Some people who have tension headaches also have a tight feeling in their jaw or neck muscles.
