Possible Foreign Object in Body

Patient: What is the appropriate doctor to go to directly find out if there is a foreign object inside of me and what is the process of removing it?BACK STORYWhen I was 12 I inserted an approximately 4 inch long, half inch diameter acrylic cylindrical object into my rectum.I’m 21 now, and I do not remember it ever coming out. I feel no pain and have had no known side effects, but want to know with certainty the object is not in my body.I also want to limit how many people know about this, so I want to cut down on my visits to the doctors office.
