BLISTERS ON THE FOOT AND HAND
Blisters are pockets of fluid that form as the skin's way of protecting itself from friction. Blisters on the feet are common injuries among hikers. Avoid getting blisters by wearing shoes or boots that fit, by changing your socks if they become sweaty or wet, and by paying attention to how your feet feel.
First Aid for Blisters
A hot spot is a warning that a blister might be forming. As soon as ou notice it, treat a hot spot or blister with a "doughnut bandage" to relieve the pressure on your skin.
Cut molesking in the shape of a doughnut and fit it around the injury. Shape several more "doughnuts" and stak them on top of the first. The doughnut bandage will keep pressure off the injury.
A gel pad mde of the same material used to treat burns can be applied directly over a blister to reduce friction and speed healing. Follow the instructions on the package. Used together, a gel pad and a moleskin doughnut provide maximum relief for blisters and hot spots.
If you must continue hiking even though you think the blister will break, it might be a good idea to drain the fluid. First, wash the skin with soap and water, then sterilize a pin in the flame of a match. Prick the blister near its lower edge and press out the liquid. Keep the wound clean with a sterile bandage or gel pad and surround it with a doughnut bandage.
