Hello to everyone here at CPN. I am new to the website and the diagnosis and have many questions. Hopefully some of you may be able to answer and help me to understand. I have been recently diagnosed with what appears to be a chronic infection as per my labs. I have high Igg and high IGA. I am not actively sick with respiratory problems, my issues are currenlty more arthritis especcially spinal related. But I have had a history of sinus infections and bronchitis type respiratory infections in the past. How does one know when they contracted the CPN? If I am infected chronically does that mean I had contracted this years ago or months or what?
