Developing itchy bumps on the body may indicate an allergic reaction. Individuals with allergic constitutions may develop allergic symptoms—including itchy bumps—upon exposure to their specific allergens or ingestion of common allergenic foods. Examples include pollen allergy, seafood allergy, and dust allergy. Additionally, if blisters appear, chickenpox may be a possibility.
