For a common cold with these symptoms, the best approach combines rest, hydration, and targeted over-the-counter (OTC) medications. Take Paracetamol or Ibuprofen to effectively reduce your fever and relieve both the headache and body aches. To clear your blocked nose, use a saline nasal spray or an OTC decongestant (like pseudoephedrine). If using a medicated nasal spray, limit it to 3 days to prevent rebound congestion. Drink plenty of fluids like water, warm broths, or herbal teas, and get ample sleep to help your immune system fight the virus. If symptoms worsen, persist beyond 10 days, or you experience breathing difficulties, please consult a healthcare provider.
