I am sorry to learn of this situation. I can provide you with some general information regarding medical malpractice claims, but to explore your case in detail, you really need to speak with a local attorney (based on what you posted, it seems like you also have claims outside of the medical malpractice claims for inappropriate conduct - if you have not already done so, you can report this conduct to the State Medical Board, but if you are going to pursue legal action, please speak with your attorney first, as this should be done strategically in conjunction with your medical malpractice case and your attorney will help you - if you are not going to pursue a civil case, please report this bad conduct, these types of professionals need to be disciplined by their governing bodies, and multiple reports are what lead to their license being removed permanently).
Medical malpractice claims are based on expert testimony, this means you, or your attorney, will need to find a medical expert in the same, or similar field, to testify as to the standard of care in the industry, whether your physician or facility's conduct fell below that standard, and whether that negligence was the cause of your injury. The same (or a different) expert can then testify as to your projected future damages and cost of medical care.
Due to the complexity of these claims, I highly recommend that you retain a medical malpractice plaintiff's lawyer (also called trial attorneys). Fortunately the majority of these attorneys will provide you with a free consultation, and many will represent you on a contingency basis (they will advance the costs of litigation and legal services in exchange for a portion of your successful settlement or judgment).
You can find local attorneys using the State and Local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
