A blister is a raised area containing fluid under the top layer of skin. Blisters are usually circular in shape. The fluid that forms underneath the skin can be blood or serum (the clear liquid portion of the blood). These fluids sometimes collect in an area of damaged cells and form a blister.

Blisters can form as a reaction to trauma to the skin or certain skin diseases, which may include the following:
|
|
|
- burns/scalds
- sunburns
- friction (from a shoe, for example)
- eczema (also known as atopic dermatitis)
- impetigo (a contagious infection of the skin)
- viral infections (including chickenpox and herpes zoster)
|
|
The symptoms of a blister may resemble other skin conditions or medical problems. Always consult your child's physician for a diagnosis.

A blister will usually heal on its own. Some general guidelines for treatment may include:
|
|
|
- Calm your child and let him/her know that you can help.
- Wash the area with soap and water.
- A cold or ice pack may help reduce swelling and discomfort.
- Keep the area clean and dry - do not burst or "pop" the blister.
- If the blister bursts, place an adhesive bandage or dressing on the area to keep it clean.
- Observe the area for signs of infection such as increased warmth, swelling, redness, drainage, or pain. If you notice any signs of infection, call your child's physician. Antibiotics may be needed.
