In any medical malpractice, you need to prove that the doctor breached what is known as the "standard of care" to establish negligence. To prove that a doctor violated the standard of care, you generally need expert testimony--generally, the testimony of another doctor. Once you are able to prove negligence, you have to prove damages. Because medical malpractice cases are so expensive, the damages generally need to be fairly high in order for an attorney to justify the economic risk of taking the case. I would suggest that you consult with a medical malpractice attorney in your state, who can then review your medical records and begin investigating whether you might have a case.
