My husband got a small shard of a glass bottle lodged in leg two days ago.Should it be removed?

A bottle was broken while he was weedeating and a small shard of the glass flew up and lodged in his calf. He says that he can feel it shifting when he’s on his feet for long periods of times. He cleaned it out well but couldn’t get to the glass to retrieve it. It doesn’t seem to be infected but I have heard that it is possible for objects that have been lodged in the body and not removed to actually travel throughout the body causing worse damage later on. Should he go to the doctor and have it removed?
