Coughing up mucus. sore throat, running and stuffy nose.

Viral: Most times these are signs of a viral respiratory illness. Unfortunately there is no cure for a virus. It needs to run it's course. The old saying is it lasts 7 days if you treat it, a week if you don't. Worrisome signs would be chest pain, shortness of breath with activity, high fevers or vomiting.

Exam: Be checked. It may be a bad virus but a productive cough suggests pneumonia. You may need antibiotics. All the best.
