For your symptoms, an over-the-counter multi-symptom cold and flu medication containing acetaminophen (for pain and fever) and a decongestant can be very effective. Alternatively, you can take paracetamol (acetaminophen) 500mg or ibuprofen 400mg every 4 to 6 hours as needed to relieve the headache, body pain, and fever. Please read product labels carefully to avoid doubling up on acetaminophen, which can cause liver damage. Ensure you rest, drink plenty of fluids, and use saline nasal sprays for congestion. If your fever lasts more than three days or symptoms worsen, please consult a doctor.
