10 Causes of a Sore Tongue
Cause #7: Food Allergy
Food allergies occur when there is an abnormal immune response to food. Depending on the severity, symptoms can range from mild to severe. Symptoms include itchiness, diarrhea, vomiting, swelling of the tongue, sore tongue, trouble breathing, low blood pressure, and hives. Symptoms appear within minutes to hours after exposure. Severe cases result in anaphylaxis, which is a serious allergic response.
Common causes of food allergies include wheat, rice, soy, eggs, shellfish, peanuts, tree nuts, and cow’s milk. It is due to the protein present in the food triggering the release of inflammatory chemicals like histamine. Management includes avoidance of triggers, giving adrenaline, allergen immunotherapy, and wearing medical alert jewelry.
