Patient's question:

There is a cough, phlegm in the throat that cannot be coughed up, and runny nose

Doctor's answer:

Hello, according to your description, acute pharyngitis is often part of an upper respiratory infection and is usually caused by a viral infection. The condition can manifest as acute simple pharyngitis or acute purulent pharyngitis. It is recommended to receive timely anti-inflammatory treatment.
There are many factors that can affect the pediatric respiratory system. If a child is diagnosed with a respiratory condition, parents need to cooperate with the doctor to start treatment immediately, assist with gastrointestinal decompression, and develop good hygiene habits. Parents should pay attention not to develop picky eating habits in their children and ensure a balanced diet.
