User avatar Hello Rayraylaws,

Almost certainly, this lump is an enlarged lymph node. The area you are describing has many lymph nodes in it and the recent ear infection may be the initial cause. As the body begins to fight off an infection, the lymph nodes will often enlarge. This is a normal reaction.

After the infection has resolved they often will reduce back down in size. If this lump becomes painful or if it continues to enlarge I would recommend that you have your son evaluated by his doctor.

Best wishes.
