What can i do about surgical tools that were not cleaned properly being used during my surgery and resulting in disease exposure

I recently had Gastric Bypass surgery in Arnot Hospital. On the day that I was set to go home I was paid a visit by the Cheif Nursing Officer and the head of Infectious Diseases, as well as my doctor, where they informed me that the tools that were used in the operating room during my surgery were not sanitized correctly, they are supposed to go through two sets of sterilization and they only went through one thus putting me at risk of exposure to different diseases, such as HIV and Hep C. They took my blood while I was there at the hospital and then given prescriptions for medications to potentially fight off HIV if I was in fact infected. These medicines make me absolutely sick to my stomach, on top of already having to deal with recuperating from surgery I have to deal with being sick every day, all day. They admitted their wrong doing and that they would cover the cost of the medications, but my insurance covers it anyways. I just don't feel that it's fair that I have to be sick every day for the next month while I take these pills to fight off something they may have given to me. And the fact that I won't know for a long time whether or not they even did. Do I have options?
