Must I Do About A Stable Pin Found At The Leg Long After Treating Second And 3rd° Burns?

Hey I have a few questions regarding my leg, just recently around 4 months ago I was sent to Edmonton in Alberta due to a tragic 2nd and 3rd degree burn. I got a skin graft. Just this week I found a staple and I believe it is stuck I don’t know that’s just what I think cuz it’s been there for months
