To determine which substance may be causing the allergic reaction, we need to consider common allergens that could cause redness and swelling when in contact with the skin.
Here are a few possibilities:
1. Poison Ivy: Poison ivy contains a substance called urushiol, which can cause an allergic reaction in susceptible individuals. It typically causes redness, swelling, and itching when it comes into contact with the skin.
2. Nickel: Some people are allergic to nickel, which is commonly found in jewelry, belt buckles, and some clothing fasteners. When the skin comes into contact with nickel, it can cause an allergic reaction that results in redness and swelling.
3. Latex: Latex allergy is relatively common and can cause skin reactions when in contact with latex products, such as gloves, balloons, or condoms. Redness, swelling, and itching are typical symptoms of a latex allergy.
4. Adhesive/bandage materials: Certain adhesive materials found in bandages, tapes, or adhesive dressings can cause an allergic reaction when applied to the skin. This may result in redness, swelling, and irritation at the site of contact.
To determine the specific substance causing the child's symptoms, it is recommended to consult with a healthcare professional or allergist who can perform specific tests, such as patch testing or skin prick tests. These tests can help identify the exact substance responsible for the allergic reaction.
