"I was positive for P41 on the western blot, but no other bands"
You may want to copy your post and post this in MedHelp's lyme forum (
http://www.medhelp.org/forums/Lyme-Disease/show/148), but also consider mentioning this to Prof. Nicolson, who has done research on lyme disease and co-infections found in lyme patients. Ticks can carry not only the lyme bacteria, but other bacterias as well. The link I gave you earlier (http://www.immed.org) is from Dr. Nicolson's website. There is a ton of information on there and I highly recommend checking it out.
You could have been bitten by a lyme infected tick when you were a child and yet not have any symptoms of lyme disease, because your immune system was healthy enough to keep the bacteria under control. Years later, you get a virus and then all of a sudden... you have symptoms of lyme (or CFS). The virus was the trigger and may or may not contribute to your symptoms and/or be a possible cause.
People who are chronically ill are the ones who seem to have the higher viral titers. Most physicians don't know too much about this.... that is why I'm thrilled that Dr. Nicolson is coming back. If you would like to read his session from when he was here in October, here are the links:
