The CT scan shows that I have several surgical clips in the right side of the pelvis. Is leaving such items in someone common?

I have been complaining of pain on my right for some time now and it¿s getting worse I went to the doctor to find out what was wrong. They did abdominal and chest X-rays, blood work (Kidney) ect¿and found nothing. The X-ray did find degenerative changes involving the lower lumbosacral spine. I was given a prescription for pain. Two days later I was still in pain and went back to the doctor''s office they ordered a CT scan the findings of the CT was that I had colonic diverticula on my left side. I had no fever or pain on my left side to indicate that there was a problem. I am being treated with an antibiotic. The CT scan did show that I have several surgical clips in the right side of the pelvis, I had surgery done in 2007on my right side it involved my colon. I am being treated with antibiotics for the colonic diverticula and noting is being said or done about the pain and discomfort on my right side.
