What are Blisters?

Blisters are usually different from other skin eruptions in the sense they are filled with a watery fluid, bursting of which exposes raw skin and causes immense pain. So care must be taken to not disturb the swollen upper epidermal layer.

What are the primary causes for the appearance of Blisters on skin?

•  Blisters are dermatological outgrowths which appear for a number of reasons ranging from burns to skin rashes, chickenpox and even due to new uncomfortable shoes.

•  Other common reasons for the appearance of a skin blister include friction in certain areas, eczema, skin allergies, shingles, and even sexually transmitted diseases like herpes.

•  Frost bites, allergic reactions to certain cosmetic products may also cause blisters.

Are Blisters easily treatable or can they be fatal? There are a few things you need to know:

•  They are usually cured without medical attention.

•  However, they are very irritating and cause great discomfort, depending on their location and if they exhibit symptoms of expanding or twitching.

•  Unexplained blisters which take a long time to heal must be brought to the dermatologist’s attention immediately. Common blisters can become septic if left open; therefore they should be bandaged up with sterilized gauze after application of antiseptic ointments.

•  Blisters cannot usually be prevented except for doing your part in reducing contact friction by wearing loose clothes and well-fitted shoes. Most blisters go away with minimal first aid care. But those caused by rare infections like Pemphigus Vulgaris (chronic blistering skin disease) require medical attention. Such infections may also lead to blisters filled with blood or pus.
