2 Years Old. Had Swollen Lymph Node. Developed Cold. Related?
Cervical lymph nodes (lymph nodes that occur in the neck region) are common in children because of repeated colds.
The lymph nodes function by mounting an immune response to any illness which is predominant in the area that they drain (for example an infection in the chest may affect the lymph nodes in the axilla)
Other causes of lymph node enlargement would be infection/inflammation of the node itself , autoimmune conditions, tumors.
Since young children your son's age are expected to have 8 to 10 colds per year and the lymph nodes respond to infection, they can potentially seem to be enlarged for long periods of time because of the repeated colds.
Normally if he remains cold free for at least 4 to 6 weeks it should decrease in size or resolve completely.
If he gets another cold while it is resolving then the size would start increasing again.
If he has a prolonged well period (6 weeks) and the node does not appear to be shrinking then you may want to take him for evaluation at your doctor.
I hope this helps , feel free to ask any other questions
But he is fine and doesnt have any other symptom. If the cause of this enlarged lymph node would be something different than the repeated colds, should he have any other symptom? What his pediatrician told me is that he would be different, loosing weight and so on.
The fact that it involves the cervical nodes which are responsible for fighting off the common cold would suggest that it is related to that.
If you want, you can measure it yourself, note the value and recheck in 4 weeks (if he has been well) to see if it has changed in size.
Hope this eases your mind, feel free to ask any other questions
