Blisters: A blister that forms as part of a skin rash may be tiny, as small as the head of a pin, or much larger, up to one-half inch wide. Blisters associated with a skin rash are typically circular-shaped and filled with a serous fluid that may leak out, forming a yellow crust. Causes include bacteria, viruses, and allergic reactions. See your doctor when you have your rash.
