Foot blisters have a variety of potential causes. A blister is a small-sized pocket that is filled with fluid. It might form after an infection with bacteria or fungus, skin burn, trauma or an insect bite.
If an individual has foot blisters, he/she might have difficulty exercising, walking or standing for extended periods of time. Luckily, there are several treatments at home that can lessen the discomfort and lower the risk for repeated formation of blisters.
What are the possible causes?
In case foot blisters develop, friction is the usual culprit. Standing or walking for several hours in a day places pressure on the soles, heels and toes. The longer one is on his/her feet during the day, the higher the risk for the formation of the blisters.
Wearing poorly fitting shoes might also be a cause. Shoes that are too tight or loose can rub on the skin. This results to friction where fluid accumulates under the upper skin layer.
Excess perspiration or moisture can also trigger the formation of foot blisters. This is likely to occur during warm weather among athletes, especially runners. Small-sized blisters form if the sweat blocks the pores in the feet.
Other causes of foot blisters include:
- Sunburn
- Allergic reaction
Wearing poorly fitting shoes might also be a cause. - Frostbite
- Exposure to chemicals such as detergents or some cosmetics
- Chickenpox
- Fungal infections
- Dyshidrotic eczema
- Herpes
- Bacterial infections
Home care for foot blisters
Make sure that the foot blisters are left intact since it is prone to infection if opened. Covering it with an adhesive bandage can provide protection as it recuperates.
If left alone, the blister will eventually harden and vanish. Until this occurs, the bubble can cause discomfort depending on its size.
Even though rupturing a blister should not be done, draining it safely can provide relief.
