My Son Was Practicing Baseball And The Baseball Touch The

my son was practicing baseball and the baseball touch the glove but bounced and hit the forehead on top of the left eye brow. we put ice immediately but his left eye lid is closed. we took him to the ER and they did a scan every thing seem fine, but it has been 1 week and his eyelid is still down. What can I do to help him fix his eyelid, he has no pain though.
