HI, thanks for using healthcare magicLymph
nodes are located at various points around the body. Because small children commonly have upper respiratory tract
infections (cough and cold, ear infections), the lymph nodes in the cervical region are commonly enlarged.
The nodes increase in size if there is any inflammatory or infectious condition in the area that it is responsible for draining.
If there was no infection detected by the doctor then you can consider giving her something for the pain such as paracetamol
A warm compress may also be helpful.
I hope this helps
