How to treat Blisters

0What are blisters and what causes them?

Blisters are small, fluid-filled bubbles on the upper most layer of the skin. The blisters on your feet are most often caused by friction, although they can also occur as a result of extreme temperatures, chemical exposure, and certain medical conditions. Increased moisture or damp conditions increase the chance of a blister forming. The blister forms to actually protect and cushion the layers of skin underneath it, allowing the skin time to heal. The fluid within the blister can also vary from plasma-like fluid leaking from the cells as the top layer separates from the layer beneath it, to blood and even pus depending on the cause. If a small blood vessel at the surface of the skin ruptures, blood will leak in to the blister, giving it a dark bluish-purple appearance.


More often than not, blisters will resolve on their own with time. Although it is tempting to pop and peel them, try to leave them alone. The roof of a blister helps to protect your skin from infection and removing it prematurely results in a wound. If you leave them alone, you will find that as new skin grows underneath it, the fluid inside the blister with reabsorb into the skin and the roof of the blister will dry and peel off naturally. While the blister is fresh, wear shoes that reduce pressure in the area of concern or avoid the shoes that caused them in the first place. In addition, covering it with a band-aid or gauze will provide added protection.

If you’re prone to blisters and you have diabetes, book an appointment with a Chiropodist today to have him or her assess your feet and treat them accordingly. Additional measures may need to be made to ensure blisters do not reoccur as they put you at risk for additional complications.


There are a number of things you can do to help prevent blisters. First and foremost, ensure you are wearing shoes that properly fit your feet and that are comfortable. If you have a new pair of shoes, gradually break them in rather than wearing them for an eight-hour day the first time you decide to wear them. Also, reduce the moisture at your feet by always wearing socks when wearing closed toe shoes, opting for moisture-wicking socks especially during exercise, and applying foot powders either directly on the foot or even sprinkling some in your socks if your feet tend to perspire excessively. Finally, if you know you are prone to blisters at a certain area on your foot, be proactive and apply a piece of moleskin to reduce friction and shear forces.

Blisters may seem like a small problem, but they can be rather painful. Pain with every step throughout your day can really impact the quality of your life.

Remember, it’s the little things that can make a big difference!
