I am sorry to hear about this. It sounds like you might have a basis for a medical malpractice suit. What i recommend is that you request your medical records from the hysterectomy and from being readmitted after the complications and start calling local attorneys in your area who handle medical malpractice suits. I think that it is worth you looking into this further and consulting with a local attorney in your area who will know more about your states requirements for medical malpractice cases. Best of luck!
