HELP!!! My dad has been recently diagnosed with a post-op infection in his L5. He had his second surgery on April 15, 2011. There was slight releif of pain, however it has since gotten worse to the point, he had to be admitted to the hospital on July 11, 2011 for IV pain meds and Vanco + Zosyn. He is home now, however there is no improvement. The pain is so bad that Norco 10mg barely touches the pain. He is not septic and the samples they took from his spine are negative for MRSA or Staph, or any other "bug" that they know of. Basically, he is being treated with these antibiotics, but there is no proof that they will kill whatever is causimg this infection. Can anyone give me some insite as to what is going on? We are confused and worried which is normal, but there is nothing "normal" about what is going on with this mysterious infection. His labs revealed that he has a touch of anemia, and the doctors told us that this was a result of the inflammation in his L5. The X-ray/MRI showed that the area is merky. Please respond if you can help us with some info. Anything will help, as we have no answers from the doctors because they don't know what is going on. We do know that he contracted this infection from his second surgery.
