"What can I do for my 4-year-old daughter who has a congested nose and a very sore ear?"

If your 4-year-old daughter has a congested nose and severe ear pain, you can try giving her nasal showers multiple times a day to help reduce the congestion. It is important to monitor her fever and consider giving her Tylenol or Advil if needed. If her ear pain doesn't improve after 72 hours or if her fever persists, it may be best to consult a doctor to check for a possible ear infection. Avoid giving cold medicine or syrups with medications to young children, as they can be ineffective and have potential side effects.
