In some cases, you may sue for what might have happened during a medical procedure and in some cases, no. The real question here is whether or not you are going to be able to prove that you sustained injuries as the result of negligent conduct during the procedure. Proving medical malpractice can be difficult, especially in cases where you do not know exactly what happened, but with a medical malpractice attorney’s investigation and expert witness opinions, proving medical malpractice may be a possibility.
