Hi,
Based on your symptoms, this is most likely an acute viral upper respiratory tract infection (viral fever/common cold), but COVID-19, influenza, or a secondary bacterial infection cannot be ruled out without an examination.
For now:
Stay well hydrated and take adequate rest.
Continue warm fluids and steam inhalation 2–3 times daily.
For fever, headache, or body ache, you may take Paracetamol 650 mg every 6–8 hours as needed (maximum 3 g/day), unless contraindicated.
Avoid taking antibiotics without a doctor's prescription.
If possible, check your temperature and oxygen saturation regularly.
Next Steps
Visit a physician within the next 24 hours for a physical examination.
You may require tests such as CBC and, depending on local prevalence and symptoms, COVID-19/Influenza testing if clinically indicated.
Seek emergency medical care immediately if you develop:
Difficulty breathing
Persistent high fever
Chest pain
Confusion or excessive drowsiness
Oxygen saturation below 94%
Health Tips
If your symptoms persist beyond 5–7 days, worsen, or new symptoms such as productive cough, severe sore throat, or persistent high fever develop, you should be re-evaluated by a doctor, as additional treatment may be required.
