Cut a vein in your wrist will it heal itself or do you need medical treatment?

If you have cut a vein in your wrist, you need to seek medical treatment immediately. A cut vein can cause significant bleeding and may require stitches or surgery to repair. Additionally, there is a risk of infection and other complications if the wound is not properly treated. Do not attempt to treat a cut vein yourself. Instead, call emergency services or go to the nearest hospital for medical attention.
