Hello. Your symptoms suggest a common viral infection, like a cold. To help reduce your fever and ease body aches, you can take paracetamol (acetaminophen) or ibuprofen. For the runny nose, an over-the-counter antihistamine like cetirizine or loratadine should provide relief. Please make sure to rest and stay well-hydrated with water and warm fluids. There is no need to panic, as these symptoms usually resolve on their own. However, if your fever persists for more than three days, worsens, or if you develop shortness of breath, please consult a doctor for a proper evaluation. Get well soon!
