. A person's own skin (or the skin of another person) may be sufficient to act as an abrasive surface to cause friction burn. More commonly, friction with abrasive surfaces, including clothing, carpet, or rope, can lead to a friction burn. Common places at which skin-to-skin chafing can occur are between the thighs and under the armpits. Friction burns are very common with clothing such as trousers on the knees caused by playing sport or sliding on wooden surfaces. Less dangerous friction burns can occur frequently on sensitive skin surfaces such as the genitals, such as during

Treatments

Most minor cases of a friction burn require little to no treatment, as a specific case of allergy might aggravate the burn. Treatments for friction burns usually involve application of an
