Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can very well understand your health concerns..
As per your query swollen preauricular lymph nodes or regional
lymphadenopathy can occur as a result of infections originating from ear and other parts of head and neck region as well as at times infection arising from distant areas of body can cause swelling in lymph nodes from lymph draining carrying infection..
As you took antibiotics and the pain subsided there are chances that the lymphadenopathy is due to infection.
As the
swollen lymph nodes takes a comparatively longer time to resolve after subsiding of infection therefore it is possible that the swelling of lymph nodes goes down after a few more days..
At times if there is no infection and the lymph nodes are persistently enlarged there can be
LYMPHOMA formation which is a cancer of lymph nodes..
An
ultrasound as well as
lymph node biopsy has to be done to confirm the diagnosis..
Hope this information helps and thanks for writing to Healthcare Magic..
