Oftentimes, even with resolution of infection, these enlarged
lymph nodes would not regress in size. Recurrent infection would make the
lymph nodes to enlarge intermittently.
Lymphomas would present with enlarged lymph nodes. This is associated with constitutional symptoms of fever, sweating, weight loss, and sometimes itchiness of the skin.
I would suggest that you continue to observe your child for any symptoms and bring her to her pediatrician for evaluation and management.
Good luck.
