What is Facial Swelling?

• Facial swelling is a generally allergic reaction that occurs when the eyes, cheeks and mouth become irritated and swell up to a size that is larger than normal. This may give all of the face or a portion of the face a strange appearance. Swelling of the face can last several minutes, or up to several days. If your face begins to swell and you're not sure why, it's best to contact your doctor as soon as possible. If you have had allergic reactions in the past or can pinpoint the reason why your face is swelling, you may be able to treat the swelling yourself.
  
  

Causes of Facial Swelling

• Causes of facial swelling include cysts or pimples that become infected; allergies, including food allergies, environmental allergens and mold allergies; edema, where the body retains water; conjunctivitis or other eye irritations; complications or recovery after jaw surgery; a tooth abscess that becomes infected; and trauma to the face, like a burn. Obesity and weight gain can also cause facial swelling. If your face has swelled to an abnormally large size in a short period of time, contact your doctor immediately, as you may be suffering a severe allergic reaction.
  
  

When to See a Doctor

• If your swelling becomes so severe that you are unable to open your eyes or mouth, or you are unable to breathe, call the doctor or 911 immediately. Sometimes swelling can be a sign of an infection, so take your temperature regularly while monitoring the swelling. If your fever reaches over 101 degrees, call the doctor. Avoid touching your face to prevent spreading if the swelling may be due to conjunctivitis, or pink eye.
