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 a 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. The skin 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.
