Can allergies cause severe facial swelling?
The answer to this question is yes, definitely. Facial swelling can be a particular symptom of oral allergy syndrome, which occurs when people with pollen allergies are exposed to certain fruits and vegetables. It's a type of cross sensitivity and is not usually severe. Antihistamines are usually effective in reducing symptoms.
However, facial swelling could also be one of the more severe anaphylaxis symptoms that can result in certain people from exposure to some foods, latex or stinging insects. If you are also having other symptoms, then immediate treatment is necessary to avoid a more severe event. Read more about anaphylaxis here
