While most cases of gooseneck barnacle injuries are relatively minor, in some cases they can lead to more serious complications. For example, if the wound becomes infected or develops a particularly strong immune response, it may result in the formation of a painful and potentially dangerous condition known as a barnacle boil. In severe cases, this can require medical treatment to prevent further complications, such as sepsis or tetanus. Therefore, it is important to seek medical attention for any gooseneck barnacle injury as soon as possible, in order to reduce the risk of long-term health effects.
