I need a doctor or lawyers opinion on this or anyone that this has happened to?

I have been sick for awhile&had a CT SCAN & they said that a large metal staple had been left in me after gall-bladder surgery& that this might be causing some of the pain i have! do doctor's leave metal staples in you after this type of surgery and if not do i have a mal-practice case or is it too late because i just found out about the staple being left inside me yesterday,but my gall-bladder surgery was about 5 years ago.I have been in pain all this time and have been diagnosed withjust about everthing and nothing has worked. please only serious answers only
