Needs Examination: Please see a physician and/or dentist as soon as possible. Swelling can cause obstruction of your airway and can cause breathing issues.

Swelling: Any bleeding, pain, or as in your case swelling, deserves immediate evaluation. Impossible to attribute a cause without evaluation. As airway swelling can lead to obstruction, the swelling must be addressed immediately. Please see your Dentist, Physician, or Urgent Care as soon as possible.
