I had PLIF and discectomey last Dec and am wondering if it is possible to have a infection this late in the game? I have had several lung and head infections, and now I am dealing with pnuemonia. I have had oral antibiotics for 7 days along with prednisone. When that didnt work, I was switched to IV antibiotics and have had 16 dailey treaments. I keep having sweats and chills and just wondering since my white count went up after I had taken oral meds for a week, if it is possible that the problem lies deeper. I am constantly tired, and my pain level has not improved in the last month. In fact, sometimes it is worse. Any thoughts on this?
