Foot Blisters: Causes, Treatments & Home Remedies

Blisters are like small boils that can appear on any part of your body, especially the hands, feet and sometimes even your face. They contain a fluid-like substance which is often mistaken for water. The possible causes of blisters include over stress on your body, sweating, wearing new shoes, and constant friction during physical activity.There is no difference between the blisters you get on your hands and feet. They are a result of gap between the innermost skin layer and the exterior skin layer.

Types of Blisters

Blisters can be categorized into three different groups:

Fever blisters, which usually occur on the face.

Blood blisters, which are usually accidental. Let’s say for example, your upper skin layer gets tucked into or pinched by some object by mistake which lifts the upper layer and creates a gap.

Friction blisters, which can be caused due to heat, open air or working in water without gloves.

Causes of Foot Blisters

Foot blisters can be caused by a number of things, they are:

  • Moisture is the biggest cause leading to the formation of foot blisters.
  • Through continuous rubbing of skin with the shoes. This applies pressure on the skin and therefore the formation.
  • A condition called athlete’s foot can also cause foot blisters. Theskin becomes itchy and then crack open. It is the result of a fungal infection.
  • Another cause of foot blisters can be Dyshidrotic eczema. Very common in women, this condition causes blisters on the bottom of the feet and palms of hands. They last around 3 weeks and occur in people who are more prone to allergies.
  • Contact dermatitis can also lead to small blisters.
  • Over-Exposure to various chemicals, dyes, fragrances, medicines can also cause blisters.
  • Poison-ivy is another irritant that can cause foot blisters.

Medical Treatments for Blisters

In most cases, a little first aid treatment should be sufficient to treat the blister, other times, you may require antibiotics or other treatments.

For the first aid treatment:

  • Take a needle and wipe it clean with alcohol;
  • Pinch the blister with the needle;
  • Press the fluid out towards the punctured area;
  • Cover the area with gauze;
  • Wait for it to heal.

Some precautions while administering first aid:

  • If you see any signs of infection, i.e. yellow pus draining out, etc., then you should see a doctor.
  • Do not drain out the blister if you are a diabetes, HIV, cancer or heart patient as these are contagious.
  • Use a donut shaped moleskin pad for the affected area. Make sure not to cover the foot blister itself. This will prevent it from exploding on its own and causing a mess.

Another medical treatment for foot blisters is to use Vitamin E pills. For this, you can just pop open the pill and apply the liquid directly on your blister. This is because Vitamin E has amazing skin healing properties and will also prevent scarring. Lastly, if you aren’t up to date on your tetanus shots, then get one to avoid further complications.
