Glass lodged in the flesh heals and needs to be taken in context to determine if it can come out on its own. Usually if the glass is shallow, it may come out on its own, but if it is deeper, it will not be able to come out on its own.
Generally speaking, if the glass is lodged in the flesh superficially, the glass will come out by itself as the wound heals. Because the human body will have an immune rejection reaction to the glass, the wound where the glass is located will have inflammation and exudate, and the wound will be difficult to heal, but with the growth of the tissues underneath the glass, the glass will be gradually pushed out of the body with the growth of the tissues.
However, if the position of the glass into the flesh is deeper, the glass will not be pushed out of the body with the growth of the tissue underneath, but with the gradual growth of the tissue on both sides of the wound, the glass will be wrapped in the body, forming a foreign body granuloma, resulting in localized pain and discomfort, which will need to be removed through surgery.
Usually contact glass must be careful to avoid scratching the human skin, good protective measures, wear good gloves. If the glass is stuck into the flesh, the glass must be removed through surgery as soon as possible to prevent the wound from becoming inflamed and infected.
