Unc chapel hill symptoms and conditions

Hi,
Back in May of 2008 my it was alleged by doctors that my mother needed to have her gallbladder removed. During the surgery, she was given Diprivan 200MG AMP, and Fentanyl 5ML vial. Since the surgery, she is yet to recover. After seeing many local doctors and surgeons, we decided to go to UNC Chapel Hill, where the doctors there cannot even tell her what is wrong. She has since (the surgery) also developed C-diff. She has had her medical records released an I'm trying to take this into my own hands as I'm tired of seeing her literally get sicker and sicker. Here's my question: Is it possible for these side effects to last over this long period of time, from just having a 5 ML vial of Fentanyl? The reason I ask is because every above listed symptom that people have had after using the medication, is what she goes through on a daily basis. Here is a small list of her daily symptoms: flue like symptoms, hot flashes, constant fatigue, sometimes diarrhea, sometimes vomiting, slurring of some words, disfunction in her language ability -- sometimes she cannot read a sentence clear on her first attempt. EXTREME short term memory loss, physical instability, as well as weakness in her body. I've researched side effects of this medication and those are all listed, and I've seen more lists above. Is it possible for her to be having long-term adverse side effects from this medication? Is it possible for her C-diff to be related to the medication? If anyone could help with anything I could greatly appreciate it. While this is risky, I'm going to put my personal email because I just need immediate help and advice from anyone, and I check my email ample amounts of time throughout the day. So, please email me if you have any suggestions. ******
