A Case on Blisters...
On my last count, I have 3 blisters on my feet. 2 on the right foot and 1 on the left. What a pain when I'm walking these few days. So to educate people more about blisters, formation and prevention, I'l just copy and paste some information here.
Cause
Blisters form when the skin rubs against another surface, causing friction. First, a tear occurs within the upper layers of the skin forming a space between the layers while leaving the surface intact. Then fluid seeps into the space. Soles and palms are most commonly affected for several reasons. The hands and feet often rub against shoes, skates, rackets, or other equipment. Blister formation usually requires thick and rather immobile epidermis, as is found in these areas. In addition, blisters form more easily on moist skin than on dry or soaked skin, and warm conditions assist blister formation.
Prevention
To prevent blisters, you need to minimize friction. For the feet, this begins with appropriate shoe and sock selection. Make sure your shoes are the right size and shape. Wear socks made from synthetic blends. Before you exercise, apply petroleum jelly or talcum power to reduce friction, if needed.
Blister Care
If you get a blister, you'll want to relieve your pain, keep the blister from enlarging, and avoid 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, intact blisters that don't cause discomfort usually need no treatment. The best protection against infection is a blister's own skin. Larger or painful blisters that are intact should be drained without removing the roof. First clean the blister with rubbing alcohol or antibiotic soap and water. Then heat a straight pin or safety pin over a flame until the pin glows red, and allow it to cool before puncturing a small hole at the edge of the blister. Drain the fluid with gentle pressure, then apply an antibiotic ointment such as bacitracin with polymyxin B (double antibiotic ointment) or bacitracin alone. Avoid ointments that contain neomycin because they are more likely to cause an allergic reaction. Finally, cover the blister with a bandage. Change the dressing daily.
Well, that's all for now. Do you feel educated and enlightened? Thank me.
