What are common symptoms of a minor allergic reaction?

Skin irritation and hives are indeed common symptoms of a minor allergic reaction. When an individual has a mild allergic reaction, the immune system responds to an allergen by producing certain antibodies, which can lead to localized reactions such as redness, itching, or raised welts on the skin, commonly referred to as hives. These symptoms typically indicate that the body is reacting to a substance it deems harmful, but they do not involve severe systemic responses.

In contrast, the other options represent symptoms associated with more severe allergic reactions. Difficulty breathing and swelling can indicate anaphylaxis, a life-threatening reaction that requires immediate medical attention. Severe dizziness and shock are also signs of a serious allergic reaction or shock, which are not typical of minor reactions. Nausea and vomiting may occur with some allergic reactions or food intolerances, but they do not specifically define the most common symptoms of a minor allergic reaction.
