The German Society of Neurology pointed out that tension headache is the most common type of headache, characterized by a pressing pain on both sides of the head. It added that potential causes of tension headaches include the presence of sensitive pain trigger points in the muscles of the head, neck, and shoulders, sensitivity to light and noise, changes in blood and nerve fluids, and disturbed venous blood flow caused by psychological stress, infections accompanied by fever, and muscular strain. In cases of chronic troubles, genetic factors may be involved. Diagnosis relies on the physician recording the medical history and checking specific diagnostic criteria (duration, symptoms, ruling out other diseases), neurological examination, blood pressure measurement, and possibly blood or cerebrospinal fluid analysis. Tension headaches are treated with over-the-counter pain relievers for a short period, applying diluted peppermint oil to the temples and neck, and home remedies for mild symptoms (such as willow bark preparations), in addition to engaging in endurance sports like running or training the shoulder and neck muscles, and relaxation techniques such as yoga and meditation. In cases of chronic tension headaches, pharmacological treatment may include antidepressants, anticonvulsants, muscle relaxants, as well as psychological therapy.
