Lymph is a type of bodily fluid which is clear and very watery. It is the most basic part of the lymphatic system, which consists of larger bodily structures, such as lymph nodes and lymph ducts. This fluid is typically seen along with blood in injuries and is common in the healing process.
Lymph fluid is commonly released during the healing process of piercings and modifications around the head and neck. This is because of the proximity of certain veins, glands, and lymph nodes, which are located in the neck and throat.
