Common Symptoms of Oral Allergy Syndrome
Symptoms of oral allergy syndrome can be mild or severe. They usually start right after eating the problem food. Common signs include itching or swelling in the mouth, lips, tongue, or throat.
In some cases, reactions can be more serious. But anaphylaxis is very rare.
| Symptom | Description |
