Blisters are quite common for anyone who regularly participates in sports. Most athletes just accept them as the price you pay to play, 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 seperate 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 and create friction and these moist, warm conditions are perfect for blisters.

Prevention
To prevent blisters, the goal is to minimize friction. Appropriate footwear, and socks will help reduce blisters. Make sure your shoes are the right size and shape. Wear socks made from synthetic blends. You can also apply petroleum jelly or talcum power before exercise to reduce friction.

Blister Care
If you get a blister, the goal is to 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, and red streaks leading away from the blister). Small unbroken blisters that don't cause discomfort can be left alone to heal, because the best protection against infection is a blister's own skin. Large, painful blisters can be drained but don't remove the top layer of skin.

First clean the blister with rubbing 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.
