What is the reason for a child's recurrent fever with sore hands and feet?

Patient's question:

Fever for 4 days, recurring

Doctor's answer:

Hello, the symptoms are suspected to be caused by the influenza virus attacking the joints. It is recommended to take diclofenac orally for treatment.
There are many reasons that can cause respiratory problems in children. If a child is diagnosed with respiratory issues, parents need to cooperate with the doctor in active treatment, assist with gastrointestinal decompression, and develop good hygiene habits. Parents should pay attention not to develop picky eating habits in their children and maintain a balanced diet.
