In the large scheme of life, blisters may not seem anything to worry about. These tough pillows of damaged skin filled with clear yellow fluid can appear anywhere on the body, although they are more likely to occur on the feet, especially when poorly fitting tight shoes are worn. But to ignore them can lead to problems like infections.
What you should ignore is any urge you may get to stick a pin or needle in its pillow of thick skin to drain it of its clear yellow fluid in an attempt to hurry the healing process. It's a sure way to invite infection. And don't pick at the edges or peel the skin away when it finally bursts — on its own. And it will burst and heal if left alone, but it will take anywhere from three to seven days.
