I have a sore throat, I'm coughing, my nose is blocked, and my chest hurts?

Yes, it is possible to suggest using nasal hygiene with saline solutions like Hydrasense or Sinus Rinse to help with congestion and mucus in the throat. It can be done multiple times a day, including before bedtime. Throat lozenges like Halls or Fisherman's Friend can also provide relief for throat irritation. If your symptoms persist or worsen, it is advisable to consult a doctor for further evaluation. A cold typically lasts 5-10 days, so monitor your symptoms and seek medical advice if needed.
