Thanks for your reply, Karl. Our ID sent cultures to Jewish in Denver, so we did get more detailed info from them. Don't think he's had a CRP lately, but good reminder to ask them to check it. Have an appt at Mayo in November to have them weigh in on his treatment. He's been a patient there before for complicated total knee revision with infection. Sounds like you've learned the importance of being your own healthcare advocate as we have!
I have learned a lot through this. I do not trust anyone blindly any more.
