Fever is generally not a common symptom of allergic reactions. Allergies are immune responses that occur when the immune system overreacts to harmless substances, such as certain foods, medications, or environmental triggers like pollen or pet dander. The typical symptoms of an allergic reaction can include:

1. Skin reactions: This may include itching, redness, hives, or swelling (angioedema) of the skin.

2. Respiratory symptoms: Allergies can affect the respiratory system and result in symptoms like coughing, sneezing, a runny or stuffy nose, and shortness of breath.

3. Eye symptoms: Allergic reactions often cause itchy, watery, or swollen eyes, a condition known as allergic conjunctivitis.

4. Gastrointestinal symptoms: Some people may experience gastrointestinal symptoms like nausea, vomiting, abdominal pain, or diarrhea as a result of an allergic reaction, particularly after ingesting certain foods.

5. Anaphylaxis: In severe cases, an allergic reaction can lead to a life-threatening condition called anaphylaxis. Symptoms of anaphylaxis can include difficulty breathing, tightness in the throat, chest pain, dizziness or lightheadedness, rapid pulse, and a drop in blood pressure. Anaphylaxis requires immediate medical attention.

While fever is not typically considered a symptom of allergies, it's important to remember that different individuals may exhibit varying degrees of symptoms, and there can be exceptions or additional symptoms in certain cases. It's always best to consult with a healthcare professional or reference reputable sources for accurate information when writing an essay.
