Blisters are fluid-filled bumps that appear on your skin when it has experienced friction. You may get them on your feet after walking around in shoes that are too tight, or on your hands after spending a day shoveling in the garden. If you get a blister, it's important to know how to treat it at home, so that it can heal quickly and you can avoid infection.

However, there may be times when you do need to seek medical attention for a large or infected blister.
