Thanks for the information, I'm sorry for the delay in my response, I hadn't seen the notification!
First of all, I suggest lozenges like Halls or Fisherman's Friend if needed, for local relief of throat irritation.
If your ears are not completely blocked, I strongly suggest nasal hygiene with a saline solution (Hydrasense, Sinus Rinse and others), which can be done as often as needed during the day, and at least 30 minutes before bedtime. By 'cleaning' the nasal secretions, we can reduce the backward flow of secretions into the throat that often causes coughing. It's a bit unpleasant but it works wonders!
I also encourage you to drink a lot of liquids, cold or hot, depending on your preference.
If the symptoms persist for more than 7 days without improvement, you should consult a doctor.
I hope I've been helpful and I'm available if you have any other questions!
