Friction burns occur when skin rubs against a rough surface, causing damage to the outer layer of skin. This type of injury can happen during activities like sports, falls, or accidents involving vehicles. The intensity of the burn depends on the speed and pressure of the friction, as well as the surface involved. Symptoms of friction burns include redness, swelling, and pain in the affected area. In some cases, blisters may form, and the skin can become raw or open. Proper treatment involves cleaning the wound, applying antiseptic, and covering it to prevent infection. If severe, medical attention may be necessary.
