How are they caused?
Blisters are caused by friction from shoes or clothing, which repeatedly rubs on the skin causing friction burns. As the outer layer of skin separates from the inner layers, the space fills with lymph fluid.
Blisters are a common problem with athletes wearing in new shoes as well as athletes or walkers who take part in exceptionally long events such as marathons or endurance walks. Blisters DO NOT need to be a normal part of sporting life and they can be prevented.
How do I prevent them?
- Ensure that shoes fit correctly
- Keep feet as dry as possible. Wet shoes and socks will cause blisters far quicker that dry ones.
- Whenever possible change socks and use a power to keep your feet dry
- Protect potential “hot spots” with a second skin (bandage) or tape
What do I do if I have a blister?
- If possible, do not “pop” the blister, however…
- If the blister is on an area of high pressure and it has not “popped”, then it may be necessary to make a small hole at the edge of the blister with a pin or needle. The pin or needle can be sterilized by passing it through a flame.
- Do not drain a blood filled blister
- Drain the fluid and leave as much of the skin as possible covering the wound. This will help protect the area from infection.
- Clean the blister with a sterilising wipe and cover with a second skin or blister plaster
- For additional security, apply tape over the top of the dressing
