What symptom may not be commonly associated with tension headaches?

Tension headaches are characterized by a specific set of symptoms, including a mild to moderate headache, often described as a band-like pressure around the head, and tenderness in the neck and scalp muscles. While nausea can occur in various types of headaches, including migraines, it is not typically associated with tension headaches.

Visual disturbances, such as aura or changes in vision, are more frequently linked to migraines. Mild neck pain is commonly reported as tension headaches often involve muscle tightness and discomfort. Therefore, since nausea is less commonly associated with tension headaches compared to the other symptoms listed, it is the symptom that stands out as potentially misleading for someone identifying the typical characteristics of tension headaches.
