You could be having an enlarged pre-auricular lymph node or an enlarged parotid gland
. This can be confirmed only after doing a thorough examination. The enlarged lymph node
could be due to infection in the surrounding region or inside the ear. Secondly, if it is a parotid swelling then there could be blockage in the duct supplying the saliva into the mouth. A local examination of the lesion and ultrasound
of the swelling can confirm the diagnosis.
