W45: Foreign body or object entering through skin

The group of conditions classified under the title "Foreign body or object entering through skin" generally refers to instances where an external item becomes lodged within the skin or the tissues beneath. This can occur due to a multitude of circumstances such as accidents, injuries, or during certain medical procedures. The nature and type of foreign body can significantly impact the symptoms. Common symptoms usually include pain at the entry site, swelling, and sometimes redness or irritation. In more severe cases, an infection may develop which may lead to increased pain, pus formation, and even fever. The progression of these conditions depends upon the nature of the foreign body, its size and location, and individual health conditions. Any part of the body that has skin can be affected by this condition. Notably, small splinters, shards of glass, or metal fragments are common examples of foreign bodies.
