Infections, allergic reactions, and traumas are a few possible reasons of face edema. On rare occasions, it may indicate anaphylaxis, a
potentially fatal allergic reaction. Facial edema can arise from a variety of sources, such as allergies, infections, and traumas. Certain
reasons might be rather dangerous and need prompt medical treatment, although others are moderate and easily treated. If your face swelling
persists for more than a few days or appears in conjunction with other symptoms, consult a physician. If you have severe
symptoms like trouble breathing, a low heart rate, disorientation, or slurred speech, get medical help right away. Anaphylaxis is a severe allergic response that can be lethal, and
these symptoms could be indicative of it. It's particularly critical to get medical help right once if someone with a confirmed cancer diagnosis experiences these kinds of symptoms.
