Facial swelling involves an accumulation of fluid in the face, which may extend to the neck and upper arms.

If the facial swelling is mild, it may be hard to detect. To assist the health care provider in diagnosing the cause, it is important to note the following:

• Whether there is pain
• The duration of the swelling
• What makes it better or worse
• Any other symptoms that accompany the swelling

• Obesity
• Allergic reaction (such as allergic rhinitis, hay fever, or a bee sting)
• Conjunctivitis with swelling around the eye(s)
• Stye with swelling around the infected eye
• Malnutrition (when severe)
• Sinusitis
• Facial trauma or injury (such as burns)
• Drugs including prolonged use or allergic reaction to aspirin, antipyretics, penicillin, sulfa, glucocorticoids, or other drugs
• Blood transfusion reaction
• Head, nose, or jaw surgery
• Angioedema from any cause including reaction to contrast media from radiologic tests
• Cellulitis
• Tooth abscess

Apply cold compresses to reduce swelling from an injury. Raise the head of the bed (or use extra pillows) to help reduce facial swelling.

• There is acute, sudden, painful, or severe facial swelling.
• There is prolonged facial swelling, particularly if it is getting worse over time.
• There is any difficulty breathing.

If facial swelling is caused by burns, or respiratory distress is present, emergency measures must be taken first. Then the medical history will be obtained and a physical examination performed.

Medical history questions documenting facial swelling in detail may include the following:

• How long has the facial swelling lasted?
• When did it begin?
• What makes it worse?
• What makes it better?
• What is your height and weight?
• How is your diet?

• Have you had recent facial injury?
• Have you had a recent test or surgical procedure?
• What other symptoms are also present? Especially, is there:
  • Facial pain
  • Sneezing
