A tension headache (TH) is the most common type of headache. The symptoms of TH involve a mild to moderate intensity headache that affects both sides of the head and usually feels like pressure or tightness around the head. It is pain or discomfort in the head, scalp, or neck, and is often associated with muscle tightness in these areas. THs occur when neck and scalp muscles become tense or contract. The muscle contractions can be a response to stress, depression, head injury, or anxiety. Any activity that causes the head to be held in one position for a long time without moving can cause a headache.

The pathologic basis of TH is most likely derived from a combination of personal factors, environmental factors, and alteration of both peripheral and central pain pathways. Peripheral pain pathways receive pain signals from pericranial myofascial tissue and alteration of this pathway likely underlies episodic tension-type headache (ETTH). Treatment for TH includes acute therapy for individual attacks and preventive treatment to minimize the number of attacks that occur. Acute and preventive treatment can be used together. The current pharmacotherapy is non-specific and includes simple analgesics and non-steroidal anti-inflammatory drugs (NSAIDs) for the episodic form and the tricyclic antidepressant amitriptyline for the chronic form. The popular targets are summarized below.
