For your mild fever and sore throat, you can take paracetamol or ibuprofen to help reduce the temperature and ease the pain when swallowing. For cold symptoms, a saline nasal spray can clear congestion, and over-the-counter throat lozenges or warm salt water gargles can soothe throat irritation. Please rest and stay well-hydrated with warm fluids. Since your fever is mild, these simple measures should help you feel better soon. If your fever rises significantly, or if your symptoms worsen or persist beyond a week, please consult a doctor for a physical examination.
