Podiatry for a foreign body will start with a full account of the history of the concern, including the events leading up to the pain, and a thorough medical and social history taking. If a foreign body is detected, the podiatrists will clean the area and attempt to remove the foreign body gently in a sterile environment and under a magnifying lamp.

Sometimes if foreign bodies are particularly fragile or superficial not causing pain, it may be advised to offload the area with suitable padding and wait for nature to take its course and the body will push it out.
