Severe headache and fever: what to know

A viral infection such as COVID-19 or a common cold can cause fever and head pain. Heat exposure and dehydration can add to the discomfort. Sinus inflammation may cause pressure around the face, while dengue is another illness considered in the UAE and travel settings. Fever with a stiff neck, confusion, marked drowsiness, or a rash can signal a serious infection and requires urgent assessment.

Rest somewhere cool, drink small amounts frequently, and note your temperature, pain pattern, and other symptoms. Limit close contact with others while fever is present and follow local testing advice if respiratory symptoms occur. Use a suitable fever medicine only as directed on its label or by a clinician. Tell the clinician about recent travel, mosquito exposure, new medicines, and immune problems.

Seek emergency care for a sudden worst-ever headache, stiff neck, confusion, fainting, seizure, new weakness, trouble speaking, severe breathing difficulty, persistent vomiting, or a rapidly spreading rash. Seek prompt medical review if fever persists, the headache is worsening, you cannot keep fluids down, or you are unusually sleepy.
