Go to a hospital with a plastic or hand surgeon immediately if you have:
• A deep cut that gapes open or shows yellow fat, tendon or bone
• Numbness or tingling in a finger after an injury
• Inability to bend or straighten a finger or the thumb
• A finger that looks pale, white, blue or cold after injury
• Heavy bleeding that doesn’t stop with pressure
• A partly or fully cut-off finger, thumb or hand
• A crush injury with severe swelling, a deformed shape or a lot of pain
• A deep cut from a machine, a dirty wound or a bite, which can get infected quickly
• Signs of infection, such as spreading redness, swelling, pus, fever or throbbing pain
If you are unsure, it is safer to be seen. Some injuries, such as a divided tendon or nerve, do not look
dramatic at first.
