[|Human|] hi i have a small almost movable lump behind my left ear that left after i got rid of an ear infection but came back but is now going back down, there is a hard lump behind the right ear that came up really fast, but is now shrinking a lot and isnt very larger anymore. I have a lot of sore throats in the mornings that go away, and smoetimes have a cough. Should i be worried?
[|AI|]  Hello and welcome to Chat Doctor, A history of ear infection followed by lymph node enlargement behind the ear suggests reactive hyperplasia of the post-auricular (behind ear) lymph node. The lymph node behind the right ear could also be reactive in nature. Investigations- especially aspiration cytology of the lesion is required to confirm the reactive nature of these lesions. Soreness of throat could be due to infection and this could lead to lymph node enlargement. Thanks and take care Chat Doctor.
