Continuous fever with inflammation in the small intestine, what's going on?

Patient's question:

Continuous low fever of 37~37.6 for days, used to have frequent stomach pain

Doctor's answer:

This is the symptom caused by mesenteric lymph node enlargement. It is recommended to take Amoxicillin and 654-2 orally for treatment. When fever occurs, it is recommended to take Naproxen orally for treatment. There are many triggers that can cause respiratory problems in children. If a child is confirmed to have respiratory issues, parents need to cooperate with the doctor for immediate treatment, cooperate with gastrointestinal decompression, and develop good hygiene habits. Parents should pay attention not to develop picky eating habits in children and maintain a balanced diet.
