Banging headache: what to know

Pounding pain may occur with a migraine, a viral illness, nasal or sinus symptoms, dehydration, heat exhaustion, stress, poor sleep, or missed meals. A headache alone cannot identify one cause. Notice whether pain is one-sided or widespread, when it began, whether light or sound bothers you, and whether nausea, fever, blocked nose, thirst, dizziness, or anxiety are present.

A headache during a common cold, COVID-19, allergic rhinitis, or chronic sinusitis can accompany the wider illness. Dehydration and heat exhaustion may also bring thirst, weakness, dizziness, or heavy sweating; moving to a cool place and drinking fluids may be appropriate while you arrange advice.

Rest in a quiet, dim room if light or noise worsens the pain. Drink fluids, eat if you have missed a meal, and take a break from screens. A cool cloth on the forehead may be soothing. If you use an over-the-counter pain medicine, follow its label and check with a pharmacist if you are pregnant, have another illness, take regular medicines, or are unsure which product is suitable.

Keep a brief record of timing, triggers, associated symptoms, and medicines taken. Repeated use of pain medicines can itself contribute to recurring headaches, so frequent headaches deserve clinical review.

Seek emergency help for a sudden, extremely severe headache, or headache after a significant head injury, especially with fainting, confusion, weakness, trouble speaking, seizure, stiff neck, repeated vomiting, or new vision loss. Obtain prompt medical advice for a new or steadily worsening pattern, persistent fever, severe dehydration symptoms, or a headache that does not improve as expected.

Tell the clinician when the headache started, its location and quality, associated symptoms, recent heat exposure or illness, fluid and food intake, sleep, stress, and all medicines used. Ask whether your pattern fits migraine, an infection, dehydration, or another cause and what follow-up plan is appropriate.
