Severe headache after dengue: what to know

Recovery can leave you weak and dehydrated, and either can intensify head pain. Fever may also have another cause, such as COVID-19 or a common cold. Dengue itself needs careful monitoring because symptoms can change around the time fever settles. A headache with confusion, unusual sleepiness, repeated vomiting, bleeding, severe belly pain, or breathing difficulty is not a symptom to watch at home.

Rest in a cool place and take small, frequent sips of water or an oral rehydration drink if you can keep fluids down. Record your temperature, headache pattern, urine output, and any new symptoms. Do not start aspirin or ibuprofen unless a clinician specifically tells you to, because dengue can involve bleeding. Arrange prompt medical advice and mention when dengue was diagnosed and which medicines you used.

Seek emergency care for a sudden, extreme headache, fainting, confusion, a stiff neck, seizure, weakness on one side, trouble speaking, repeated vomiting, bleeding, black stools, severe abdominal pain, cold clammy skin, or difficulty breathing. Get same-day medical advice if the pain remains severe, returns after improving, or you are unable to drink.

Could dehydration or a dengue complication explain this pain? Which pain relievers are suitable for me? Do I need an examination or blood tests? What changes should prompt immediate return?
