Sports Injuries: Blisters
Blisters are quite common for anyone who regularly participates in sports, but there are measures to avoid them, or decrease the pain and risk of infection if you get one.
Cause
Blisters typically develop when their is friction and irritation to the surface layer of the skin and cause it to separate from the second layer. Fluid fills in the space between these two layers. You get blisters most often on the soles of the feet and palms of the hands The hands and feet often rub against shoes, socks or sports equipment such as javelins and handle bars and create friction and these moist, warm conditions are perfect for blisters.
Prevention
To prevent blisters, the goal is to minimise friction. Appropriate footwear and socks will help reduce blisters. Make sure your shoes are the right size and shape, not too small and not too big. Wear socks made from synthetic blends, if participating in a sport such as mountain climbing or fell walking then one suggestion it to wear two pairs of socks, one thin and one thick. This way friction is created between these layers rather than your skin.
Blister Care
If you get a blister, it is best to try and keep the blister from getting bigger and avoiding infection.
Signs of infection include;
- pus draining from the blister,
- very red or warm skin around the blister,
- red streaks leading away from the blister
Small unbroken blisters that do not cause discomfort can be left alone to heal, as the best protection against infection is a blister's own skin.
Large, painful blisters can be drained but do not remove the top layer of skin. First clean the blister with rubbing with alcohol or antibiotic soap and water. Then sterilize a needle over a flame until the tip glows red; allow it to cool, and the puncture a small hole at the edge of the blister. Drain the fluid by applying gentle pressure. Put a bit of antibiotic ointment on the blister and cover with a bandage.
