Quick Summary

A tension headache is characterized by mild to moderate pain on both sides of the head, often accompanied by muscle contraction in the neck and scalp. These headaches are the most common type and are typically caused by sustained muscle contraction or the dilation of extracranial arteries. Factors contributing to tension headaches include fatigue, stress, frustration, anxiety, and depression. While usually not severe enough to require medical attention, they can be treated with mild analgesics like aspirin or acetaminophen. Chronic daily headaches share similar features but occur more frequently and can be linked to depression, anxiety, or excessive pain medication use.123
