If you have thick nasal mucus, cough, sore throat, and mucus but your chest is clear, it is usually due to an upper respiratory infection or sinus/allergy issue like Sinusitis or Common Cold; you can take steam inhalation 2?3 times daily, drink warm fluids, salt water gargles, and keep yourself hydrated, but if symptoms last more than a week, worsen, or you develop fever or breathing difficulty, consult a doctor for proper treatment.

Breathing issues with cough can be due to infections, allergies, or conditions like Bronchitis or Asthma, so you can take simple relief like cetirizine for allergy or paracetamol if fever is present, along with steam inhalation and good hydration. If you have wheezing, severe breathlessness, chest pain, or symptoms lasting more than a few days, consult a doctor immediately for proper treatment.

A cough with congested/noisy sounds is often due to mucus in the airways (like in Bronchitis), so medicines that help loosen mucus such as ambroxol or guaifenesin can be useful if prescribed by the doctor, along with steam inhalation and good hydration.
