If you cannot control the bleeding from a cut or scrape (abrasion), it is important to seek medical attention. Any cut that goes beyond the top layer of skin or is deep enough to see into might need stitches (sutures), and should be seen by a doctor as soon as possible. Generally, the sooner the wound is sutured, the lower the risk of infection. Ideally, Dr. Zaydon says, wounds should be repaired within six hours of the injury. People with suppressed immune systems are more likely to develop a wound infection and should be seen by a doctor. People who are on blood thinning medication and cannot control the bleeding should be seen by a doctor immediately. Abrasions may lead to scarring. The good news is that plastic surgery can help to remove such scars, or at least reduce their visibility. Read more about plastic surgery for scars in Miami.
