What should I do if my baby has had three and a half months of swollen lymph nodes behind the ears that haven't gone down?

Patient's question:

The baby has had three and a half months of swollen lymph nodes behind the ears, but it hasn't gone away. What was the treatment history and effectiveness: didn't care about any help: how to make the lymph nodes shrink

Doctor's answer:

The child is only one year old, with thin skin and scarce subcutaneous fat, so many normal subcutaneous lymph nodes can be palpated. This does not indicate illness, so there is no need to worry if it is not a problem.
Advice: If the lymph nodes are normal, they should be soft and smooth, with no local adhesion. Avoid frequent touching to prevent lymph node inflammation. If there is local redness, swelling, or tenderness, antibiotic treatment for one week may be applied.
