Facial inflammation is a condition in which fluid builds up in the facial tissues, states MedlinePlus. The swelling may also extend to the areas around the neck and upper arms. When diagnosing the cause of facial swelling, a doctor may ask the patient various questions regarding the symptoms of his condition, Healthgrades explains. The doctor may want to know the exact spot of the inflammation, when the swelling occurred and whether the inflammation is constant or sporadic. Doctors may also ask if the patient is experiencing symptoms such as pain and shortness of breath and might also want to know the patient's medical history.
