What Is A Blister?
They are bubbles that pop up when fluid collects in pockets under the top layer of your skin. They can be filled with pus, blood, or the clear, watery part of your blood called serum. Most are shaped like circles. Depending on the cause, your blister could itch or hurt a lot or a little. They can appear as a single bubble or in clusters.
Friction blisters, is one of the most common kinds of blisters. As they are named, friction blisters, 'friction' is what causes these to occur. Think back. Have you ever worn a new pair of shoes before you have broken them in? Or dug in the garden without a pair of garden gloves on your hands? Those are the kind of things that could cause a friction blister on your heel, toe, thumb or palm.
Keep It Clean and Dry
Some blisters get better on their own. Your skin absorbs the fluid, and the blister flattens and peels off. Until that happens, you can use some form of tape to help keep it from breaking open.
Don't Pop if You Don't Have To
Resist the urge to pop a blister unless it's so large - bigger than a 5-cent piece - or it is too painful that you can't get around. It that is the case, your doctor might decide to puncture it with a sterile needle to let the fluid drain out. Once popped, clean with soapy water, apply antibiotic ointment and cover with a bandage to keep it clean during the day, however the bandage needs to come off at night to let it dry.
