Blisters and chafing

Blisters are sacs filled with fluid in the outer layer of the skin. They are formed due to rubbing, heat or skin diseases. They are more common in the hands and feet.

Another name for blisters is vesicle (usually for smaller blisters) and bull (for larger ones).

How do blisters form?

Blisters often occur when there is friction (rubbing or pressure) at a particular point. For example, by rubbing with shoes.

On the other hand, a chafing is any superficial wound in the skin caused by the rubbing with something.
