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.
