I too had similar test results. I was Igm p 23 and Igg P41 positive on a western blot test from a local hospital. With these results and my symptoms, my LLMD said I had definitely been exposed at some point to the lyme bacteria.
Looking back, I'm thinking it may have been 10 years ago. I had some weird symptoms for months at a time and they would just disappear. In Spring of 2012, everything hit me at once and I was pretty sick. Feeling a lot better now but I still have some symptoms I'm trying to get rid of.
Anyway, I just wanted to mention my test results. From what I've read and talking with some very knowledgeable people on this forum, most people are not CDC positive on the western blot.
I hope you find out something with your test results. Even though my doctor said I'd been exposed, I still wish I had sent a blood sample to IGenex..........take care.
