Suggest Treatment For Swollen Lymph Nodes With Fever

I have been treated for two sinus infections since oct 2010. I would feel better for a few weeks after taking antibiotics and then back to feeling icky. I went back to doc in Jan. and he said i had a raw throat and thought I had mono but didnt test me for it since I am self pay. I completed my amoxicillin and after a few weeks went back because I still felt bad. He looked at my throat and said WOW, its still red. He couldnt tell if I was viral turning bacterial or bacterial turning viral. He prescribed me steriods and ciprofloxacin. I felt a little better and on March 10th, I went to the ER hoping to get a doctor who could figure out why I am still sick. I had a lymph node come up on the right side of my neck and the doctor described it as shotty. He tested me for mono, and it came back negative. He checked my WBC count and it was normal. He asked if I had cats and I told him yes, so he said I had cat scratch fever since I had been sick for so long. I started taking Doxycycline 8 days ago and hadn t ran fever over the course of my sickness until now. I have been running a low grade fever for 4 days, a have a red, circle patch that came up on the back of my neck since friday and its next to a lymph node and I have little red bumps, that look like little pimples that have started all over my body for two days. They don t itch, and are spread out. Should I wait for a few more days after I am done with this antibiotic, or go have some tests ran? I am so tired of being sick, please help.
