Almost everyone has had a blister at one time or another. Most blisters on the feet are caused by caused by friction and are relatively easily dealt with. If left alone, new skin will form underneath the affected area and the fluid that has built up in the blister will be simply absorbed back into the body. Ordinary blisters can be soothed by vitamin E ointment or an aloe-based cream.
Blisters should not be punctured, unless it is large and/or painful. If it does become necessary to puncture a blister, a sterilised needle or razor blade should be used, after washing the area thoroughly. A small dab of hydrogen peroxide (bleach) will help to protect against infection. The skin over a punctured blister should not be removed, and the affected area should be covered with a bandage. If the fluid is white or yellow, the blister is infected and needs medical attention.
You can take steps to prevent blisters with some simple measures:
- Break in new shoes gradually, and protect any areas that are being rubbed
- Wear socks that have heels instead of tube socks (which can bunch up and cause blisters). Acrylic and other synthetic-fibre socks are less likely to cause blisters than woollen socks.
- Wash and dry your feet daily to prevent bacterial infections, such as Athlete's Foot.
