Detailed answer

When the immune system reacts to certain allergens, it can cause a variety of symptoms, including skin rashes. Common allergic skin reactions include hives, eczema, and contact dermatitis. These rashes are typically itchy, red, and may have bumps or blisters. It is important to identify and avoid the allergen causing the reaction to prevent further outbreaks. Consulting with a healthcare professional or allergist can help determine the specific allergen and provide appropriate treatment or management options.
