Hello, thanks for using health care magic. Kids fall all the time on a daily basis and most often its only minor injuries that they sustained that do not really pose major concern. However, serious had trauma can lead to devastating complications such as bleeding inside the cranium which will cause compression of the brain and brain damage. However, this is at the extreme and goes first with repeated vomiting, drowsiness, then coma. I see that the trauma your child had is over years now and with the presentation you have described, it is less lkely to be linked to hr trauma. It is possible its an abscess that is giving her that severe pains and definitely requires an incision and drainage, or it could be that she had another trauma which you are not aware of and the area got swollen. It will be necessary to see a doctor for an evaluation and for appropriate treatment. Best regards Dr Achuo
