Usually, scratching the skin yourself is not considered an open wound; if the scratch is serious and has exposed tissues such as muscles and blood vessels under the skin, it is an open wound. Open wounds are injuries where the internal tissues of the injured area, such as muscles, tendons, bones, blood vessels and nerves, are connected to the outside world. 1. Scratching usually does not cause damage to internal tissues such as muscles, and the damage is mostly a mild skin laceration, not an open wound. 2. However, if there is more bleeding for a long time, abnormal sensation, abnormal limb movement, etc., there may be damage to the blood vessels and nerves, which can be called an open injury, and it is recommended to go to the hospital in time to investigate the damage, and if there is a clear damage to the blood vessels and nerves, it is necessary to carry out surgical treatment. After being scratched, it is recommended to consult a doctor in time.
