If an injury does not stop bleeding right away, you must seek immediate medical attention. Losing too much blood can cause an injured person to go into shock, which is a medical emergency. When you visit our urgent care center for acute bleeding, a provider will assess the injury and provide appropriate treatment. If you have a deep wound, you may need stitches to close it and stop the bleeding. Nose bleeds that do not stop after 20 minutes should also be assessed by a provider. Many nose bleeds occur after exposure to cold temperatures or dry air, but they can also occur as the result of a nasal injury or complication of another illness.
