Tension-type headaches are a common form of headache characterized by a dull, aching pain and a feeling of tightness or pressure around the forehead or back of the head and neck. They can occur occasionally or become chronic, lasting from 30 minutes to several days. Stress, poor posture, and muscle tension are often contributing factors. These headaches are not usually accompanied by nausea or vomiting, distinguishing them from other types like migraines. Treatment options include over-the-counter pain relievers, relaxation techniques, and lifestyle changes to reduce stress and improve posture. Regular exercise and adequate hydration can also help prevent their occurrence.
