A<unk>  (also known as a sliver) is a fragment of a larger object, or a foreign body that penetrates or is purposely injected into a body. The foreign body must be lodged inside tissue to be considered a<unk> .<unk> s may cause initial pain through ripping of flesh and muscle, infection through bacteria on the foreign object, and severe internal damage through migration to vital organs or bone over time.<unk> s commonly consist of wood, but there are many other types. According to the American Academy of Family Physicians (AAFP), other common types of<unk> s are glass, plastic, metal, and spines of animals. As with any wound that breaks the skin,<unk> s can lead to infection, which if left untreated could develop into more serious complications. If a<unk>  is in the body for more than 2–3 days, or if the wound shows signs of inflammation or tenderness (whether the<unk>  was removed or not), advice should be sought from a doctor.
