friction blisters

Friction blisters are small fluid-filled bubbles that form on the skin when it experiences repeated rubbing or friction, often during physical activities like walking or running. The friction causes the outer layer of skin to separate from the layers underneath, leading to a buildup of fluid in the space. This protective response helps cushion the damaged area, but blisters can be painful and sensitive. To prevent them, it’s essential to wear well-fitting shoes and use protective gear. If a blister forms, keep it clean and dry, and avoid popping it to reduce the risk of infection.
