For a mild fever and cold, the best approach is rest and staying well-hydrated. To reduce the fever and ease body aches, you can take paracetamol (acetaminophen) or ibuprofen, strictly following the dosage instructions on the package. For nasal congestion, saline nasal sprays or oral decongestants can provide relief. These symptoms are typically viral and resolve on their own within a week. Please avoid antibiotics, as they do not work against viruses. If your fever rises significantly, or if you develop breathing difficulties or worsening symptoms, please consult a doctor for a proper evaluation.
