Skin rash blisters are fluid-filled bumps that look like bubbles on the skin. Home blister treatment for this is often all that is needed for this type of blister. Other types of injuries to the skin may cause a blister, such as exposure to heat, electricity, chemicals, and radiation from the sun, or friction may result in burns that cause blisters. A cluster of blisters may result from severe burns, contact dermatitis, insect bites, viral infection, drug or chemical reactions, or autoimmune disorders. Exposure to cold or freezing temperatures may lead to cold injuries that cause blisters. Some spider bites, such as a bite from a brown recluse spider, cause blisters. Infection can cause either a single blister or clusters of blisters.

Causes of blisters

Of the various autoimmune disorders known to cause blistering, three are the most common. Pemphigys vulgaris, which is a potentially fatal skin disorder, causes blister. Bullous pemphigiod causes less severe eruptions that heal faster and are not life threatening. Seen mostly in the elderly. Dermatitis herpetiform causes small, itchy blisters, a chronic condition that usually starts in early adulthood. Blisters are a common symptom of many infectious illnesses, including: chickenpox, cold sores, herpes simplex, shingles, impetigo, and fungus infections.

Other possible causes

There are many possible causes of a rash and any rash needs prompt investigation by a doctor or a dermatologist. Rashes can be caused by illnesses such as viruses like that of chicken pox or systemic conditions like that of lupus, by allergies such as hives or eczema, parasites like lice in scabies, by reactions to chemicals, and by numerous other causes. One of the most feared but less common rashes is that caused by meningococcal disease, which is a characteristic hemorrhagic rash, caused by bleeding of capillaries just under the skin. Any type of hemorrhagic rash is a medical emergency.
