Based on your symptoms, you likely have a viral cold or flu. For body aches, over-the-counter pain relievers like Ibuprofen or Acetaminophen can help. For sneezing and a runny nose, an antihistamine like Loratadine or Cetirizine is effective. For a cough, you can use a cough suppressant like Dextromethorphan. Multi-symptom cold relief medications are also available, but avoid doubling up on active ingredients. Ensure you get plenty of rest, stay hydrated, and consult a doctor if your symptoms worsen, or if you develop a high fever or difficulty breathing. Please consult a pharmacist to choose the right specific brands for you.
