I can understand your concern. She may have some viral infection or bacterial infection. Due to infection she may have some reactive enlargement of lymph node. She should take a course of antibiotics. It is not respond to treatment then biopsy diagnosis is advisable. Consult your doctor and take treatment accordingly.
