Headache for three days with possible COVID-19

COVID-19 may include headache alongside fever, sore throat, cough, tiredness, muscle aches, congestion, nausea, or changes in taste or smell. Other viral illnesses, dehydration, migraine, and sinus inflammation can cause similar symptoms, so a headache is not enough to identify COVID-19.

Consider your recent exposure, symptom onset, and whether symptoms are improving or worsening. Follow current local advice about testing, staying home while unwell, and protecting people at higher risk. A positive result or strong clinical concern may change the advice you receive.

Rest, drink fluids, eat what you can, and use a suitable pain reliever according to the label. Check with a pharmacist or clinician first if you are pregnant, have long-term conditions, or take regular medicines. Avoid close contact while you have respiratory symptoms and improve airflow indoors.

Monitor breathing, alertness, temperature, fluid intake, and the direction of the headache. Contact a clinician promptly if you are at higher risk of severe illness, because treatment decisions may depend on timing and personal health factors.

Call emergency services for severe breathing difficulty, chest pressure, blue or grey lips, confusion, inability to wake, fainting, or a sudden severe headache. Seek prompt medical advice for worsening symptoms, repeated vomiting, dehydration, severe weakness, or headache that is not improving after three days.

Should I test again or arrange an examination? Which symptoms would mean I need urgent care? Am I eligible for any time-sensitive treatment, and how should I manage my regular medicines while ill?
