When you experience swelling in the face, it's important to identify the cause so that you can get appropriate treatment. Face swelling can be caused by a variety of things, such as allergies, sinus infection or even injury.  

Swelling in the Face - An Introduction

The face is made up of many different structures which are often delicate and complex. Swelling can occur due to trauma (e.g., laceration), allergic reaction, infections, inflammation or autoimmune disorders. When one part of your face swells up for no apparent reason it may have important implications for other areas on the same side of your body. Face swelling does not always indicate an emergency condition but it should always be evaluated by a physician who will perform diagnostic testing as necessary.

What Causes Face Swelling?

There are many different causes of face swelling including:- 

  • Trauma (e.g., laceration)
  • Allergic reaction 
  • Infections such as sinusitis, upper respiratory tract infections and cellulitis
  • Chronic inflammation such as occurs with leukemia or lymphoma and certain autoimmune disorders such as lupus 
  • Reaction to insect bites or stings that can cause swelling and pain at the site of the bite/sting  or more generalized symptoms such as rash, fever, headache, malaise and swollen lymph nodes; these symptoms may indicate an allergic reaction to a venomous insect bite/sting (e.g., bee sting)
  • Inhaled allergens such as from certain airborne pollens
  • Contact dermatitis or other specific allergies that can cause a localized but widespread rash of tiny bumps on the face and neck, accompanied by redness and swelling

What Other Symptoms Might I Experience? 

Face swelling can also be caused by mumps, an infection that typically affects the salivary glands. Mumps is a viral illness transmitted through saliva or respiratory droplets from the nose and throat. Face swelling may result from edema (fluid retention), which may have important implications for other medical conditions you might have so it's important to consult with your physician about any swollen face symptoms you experience.
