"I have a sore throat and a cough?"

It is not uncommon for a cough to take longer to decrease or disappear, as it is often the last symptom to go away even after recovering from an illness. Drinking plenty of fluids, whether cold or hot, can help. If there are nasal secretions that are still flowing down the back of your throat, nasal hygiene with saline water can be helpful. This can be done as often as necessary throughout the day to decrease the flow of secretions that often cause coughing.
