I still have swollen lymph nodes

I got sick 5.5 weeks ago. Half my face swelled up, fevers over 103.5 for 10 days. Lymph nodes in neck also swelled. The other half of my face was fine. I was admitted to the hospital and took vancomycin, and another antibiotic which I believe was an IV form of amoxicillin. The swelling in my face and around my eye went down. Discharges from my eye stopped. The swelling in my neck did not decrease. I have taken augmentin, vancomycin, clindamycin, avalox, and bactrim in the past month. I still have swollen lymph nodes just below my jaw. Hard balls can be felt there, and they are moderately painful. The swelling comes out below my jaw and makes my neck come out farther then my face. There have been at least a half dozen cultures attempted looking for bacteria, and all have been unsuccessful. I had a CT scan about a month ago, which only showed massive infection. Next week I will have another CT scan to see if the lumps have changed. It's been more than a month. Suggestions?
