First, : First, you can apply an ice pack to help decrease swelling. You can also give Ibuprofen or Acetaminophen to help with the pain. If the finger is deformed, that is a reason to go to the emergency room because that would mean the finger is broken or dislocated. Otherwise, call your child's doctor - they might want to see them in the clinic to examine the finger and possibly get an x-ray to make sure it isn't broken depending on the exam. Of course, use your judgement. If it looks bad, get her checked out.
