Hello I am a newbie with several questions. This situation is so confusing. I have been sick with neuropathy for three years. I have been to over ten doctors. The last rheumotologist tested me for chlamydia IgM and IgG. The IgM was negative but the IgG was 512:1, very high. He is prescribing azithromycin for 6-12 months. My other rheuomotogist says the high IgG is indicative of a past infection and the antibiotic will do nothing. This is scary and so confusing. Any comments would be appreciated. How have others been diagnosed with CPN?
