The two primary questions in evaluating a personal injury case are: (1) Who was responsible for whatever happened (e.g. car accident, etc...); and (2) How bad are the injuries from that event? If the other driver is 100% responsible, then the issue is how bad are your injuries from the crash. In this regard, it is very important to see your doctors and follow their advise. This will not only help you recover faster, but it will also document your injuries in the medical records.
Would have to look at the law as it existed when your settlement occurred. Presently, a settlement of a minor's claim requires court approval. The court monitors the funds, which can be used for the minor's benefit. The settlement money belongs to the minor, which the parent (who are typically appointed as the guardians of the funds) watch over, keep safe for the minor.

You should consult a medical malpractice attorney. If an object was left inside of you (that should not have been), then you likely have a claim. That said, the extent of your damages (harm) is what I would want to fully investigate first. Med mal cases are very lengthy and costly. Before heading down the med mal lawsuit road, I would want to make sure that it is financially advisable. You will be able to get all these questions (and more) answered by any good med mal attorney.
