Signs of Central Sensitization in Tension-type Headache

The goal of this observational study is to assess the pain sensitivity in tension-type headache patients. The main question it aims to answer is: \- Are signs of central sensitization present in tension-type headache? Participants will be asked to fill out baseline questionnaires and they will be assessed during 1 test moment (static and dynamic quantitative sensory testing). Researchers will compare tension-type headache patients with healthy controls to see if signs of central sensitization are only present in the tension-type headache group.
