Nail trephination is a medical procedure used to relieve pressure and pain caused by a subungual hematoma, which is a collection of blood under a fingernail or toenail. It involves creating a small hole in the nail to allow the trapped blood to escape, providing immediate relief and preventing further complications such as nail loss or infection.

Infection is the invasion and multiplication of microorganisms such as bacteria, viruses, fungi, or parasites that are not normally present within the body, potentially leading to disease. The body's immune response to infection can cause symptoms ranging from mild to severe, and understanding the mechanisms of infection is crucial for prevention and treatment.
