What do swollen lymph nodes behind ears indicate?
Such enlargement of the node behind the ear is usually due to an infection in the scalp. Your paediatrician is right in asking for an FNAC. It is a simple test and does not produce much pain - the procedure is just like an injection. A thin needle is inserted into the swelling and some fluid is withdrawn and tested under the microscope. I advise you to get it done straightaway and see your paediatrician with the result.
