It sounds like you are experiencing a common viral infection, such as a cold or mild flu. To help manage your symptoms, you can take paracetamol or ibuprofen to reduce your fever and relieve any body aches. Rest is essential to help your body recover from tiredness, and staying well-hydrated with plenty of water or warm liquids is highly recommended. These symptoms typically improve within a few days. However, if your fever persists for more than three days or if you develop more severe symptoms like difficulty breathing, please consult a doctor for a physical evaluation.

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.
