頭痛可與壓力、缺水、用眼或其他因素有關。若經常發作、持續不退或愈來愈痛，應安排醫療評估，而不是只按痛的位置猜測原因。Headaches can be associated with stress, dehydration, eye strain and other factors. Seek assessment if they recur, persist or worsen rather than judging the cause only by the location of pain.
求診前，記下發作模式Note the pattern before your visit
記下開始時間、持續多久、有沒有視力變化或噁心，以及已使用的藥物。突然出現極劇烈頭痛，或伴隨說話困難、肢體無力或神志改變，應立即求醫。Note onset, duration, vision changes, nausea and medicines used. Seek immediate medical attention for a sudden extremely severe headache, or headache with difficulty speaking, limb weakness or altered awareness.
