Thank you, LizaJane, for all the information. I have been struggling with PN for two years and am still wonder if it is Lyme's related. I tested negative on the ELISA and the Western blot but your story makes me wonder about the reliability of local lab tests. Your *edit* site is incredible--I still don't know what tests were done and this site is a great tool for help in determining what was and what needs to be done. Thank you for sharing your story and your knowledge.
