HiS welling behind the ear is due to enlarged large lymph nodes. Lemonades enlarge when there is an infection of the area it Chat Doctor.  You are having ear pain, so there is a possibility of ear infection causing painful large nodes. Get your ear examined to find out the cause, and start antibiotics. With this the swelling should come down. Regards
