An abrasion is an injury that happens when something rubs or scrapes the skin or the soft layers under the skin.
An abrasion is an injury that happens from an accident or from rubbing the same spot repeatedly. Small abrasions usually stop bleeding without help.
Most abrasions don't cause other symptoms besides the scrape itself.
Treatment depends on how deep the scrape is. It often includes gently cleaning the area and covering it with a bandage to protect it while it heals.
