Thank you for getting back with requested necessary information.
From your symptom analysis and correlating it with history that I have gathered from you I feel that this should be only reactive lymphadenopathy.
This is extremely common in general population and you need not worry about it.
Many times simple innocuous viral infections also cause this type of lymph node enlargement which gets better by itself in 6 weeks to 3 months time.
As such I can assure you that nothing serious is going on and you can just leave it alone and move forward.
Significant lymphadenopathy is defined as a lymph node with a diameter exceeding one cm for cervical and axillary nodes and 1.5 cm for inguinal nodes.
But if you develop symptoms like - prolonged fever/ unintentional weight loss/ loss of appetite/ rash/ bone pains/ pallor or spontaneous bruising/ or sudden increase in lymph node size and the lymph node becoming immobile then you approach your primary care physician for further evaluation of this probable lymph node enlargement please.
