Can I file my own medical malpractice against doctor who operated on my husband? State of Georgia

I'm not sure why you are having difficulty.  If you have any of the records, many malpractice lawyers will review them and provide a free consultation.  If you have had lawyers review the records and they will not then take the case, you should request a explanation and basis so you may understand and then disclose this to any subsequent lawyers who review.  The reality is death is a risk in any surgery especially with general anesthesia.  No one can determine if there's a viable claim or if any medical professional was negligent without review the records.  Also whether the surgeon was in private practice or worked for the VA or a public university hospital may also be a factor in why attorneys may not accept the claim.   Again, the best thing to do is find a way to get all the records and have an attorney review it all, and typcially then, attorneys will engage medical experts and medical expert review services to analyze the records.
