A comprehensive head and neck exam in migraine patients can reveal a mix of findings beyond a completely normal exam. Migraine can be associated with pericranial muscle tenderness and trigger points in the muscles of the scalp and neck, which can be elicited on palpation and may contribute to pain. In addition, some patients may have headaches with sinus-related components, so sinus tenderness can be present if sinus inflammation or referred pain is involved. Temporal arteries can be tender in some individuals, and bruits may be heard over neck vessels if there are vascular abnormalities or increased flow, though these findings would prompt consideration of other vascular disorders and appropriate evaluation. The combination of sinus tenderness, temporal artery tenderness or bruits, and trigger points reflects the range of possible exam findings in headache patients and helps distinguish a broad, multimodal pain picture from a strictly normal exam. Other options describe a more limited or absent set of findings and are less consistent with the potential spectrum seen in clinical practice.
