Help interpreting lumbar puncture results

Hi everyone, I went to see my neurologist today for the results of a lumbar puncture. I am wondering if anyone can shed any light on the results:

Borrelia IgG antibodies (EIA): negative
Borrelia IgM antibodies (EIA): positive (higher than 1.3 is positive, I had 2.2)
Borrelia IgM antibodies (Blot): questionable positive
OspC band: questionable positive
Borrelia IgG (L): negative
Borrelia IgM (L): negative
.... but my neurologist claims I don't have Lyme??? Comments?

The other finding was "identical oligoclonal bands in serum and liquor" - what is the significance of this? The lab personal scribbled a note on the findings saying "suspected oligoclonal gammopathy" - what does that mean in plain English?

Huge thanks in advance for any help!
