My Cousin Had Breast Removal 5 Years Ago. She Had

My cousin had breast removal 5 years ago. She had infection afterwards. 2 years ago she had reconstruction done, after the infection cleared. She developed a new infection. She has had this infection ever since and has been on years of antibiotics. Her doctor doesn't seem to do anything to help. She had the reconstruction reversed. She has had two scrapings. She is being packed everyday. She is tired all the time. We are scared she is going to die from this. She has talked to infectious diseases and they just keep telling her to go back to her plastic surgeon. How can we get her help?????
