Facial swelling can be a symptom of several different diseases, including sinusitis, malnutrition, a tooth abscess and direct injuries to the face, according to the National Library of Medicine. Facial swelling that involves severe pain, difficulty breathing or large amounts of swelling should be evaluated by a doctor.
The cause of mild facial swelling can be difficult to diagnose due to the many potential causes, as stated by the NLM. Precise descriptions of the location of any pain related to facial swelling are very helpful to doctors when determining the cause of this symptom. It is also helpful to mention the duration of the swelling and any other symptoms that occurred around the same time as the swelling. It is particularly important to report any fever or redness associated with facial swelling, as these can be signs of a serious infection.
