Infections

Several types of infection can lead to blisters, including impetigo, herpes and chicken pox. Blisters caused by herpes are referred to as cold sores.
Poison Ivy

Contact with poison ivy, poison oak or other irritants such as detergents, solvents or chemicals may cause blisters. This is referred to as contact dermatitis.
Autoimmune Disorders
