A blister is a local swelling of the skin that contains watery fluid and is a result of burning, irritation, or friction.
BLISTERS CAN BE CAUSED BY: - repeated rubbing of the skin, as in poorly fitting shoes
- a second degree burn from touching a hot surface, or sunburn
- viral infections, such as herpes, which cause oral or genital blisters or
- contact dermatitis due to chemical exposures, as in poison ivy
There is no need to break open a blister on purpose. Intact skin keeps bacteria out. Sometimes the blister may break spontaneously. When this happens, clean the area thoroughly with soap and water, apply an antiseptic ointment, and then apply a clean bandage. IF SIGNS OF INFECTION DEVELOP AROUND THE BLISTER, CALL YOUR DOCTOR SIGNS OF INFECTION INCLUDE: - redness around the area
- swelling
- heat
- pus or
- failure to heal in a few days
AVOID BLISTERS BY: - buying properly fitting shoes and wearing clean, well-fitting socks (This is especially important for people with diabetes or poor circulation.)
- using protective hot pads when cooking and paying close attention when around hot surfaces, using sunscreen and protective clothing outdoors
- handling all chemicals with the proper protective equipment, such as rubber gloves, and
- learning how to identify and avoid poisonous plants, such as rhus.
