I've only recently discovered this information about CPN.
I have asthma, it's not particularly severe, but it effects my life and has been getting worse instead of better, despite ever increasing medication dosages.
I went to a doctor about the connections between asthma and CPN and he seemed open to looking into it. I directed him to this site so he could do some reading and went back to him a week later. He didn't seem particularly convinced but agreed to prescribe me some Azithromycin and Doxycycline. The dosages didn't follow any of the recommended treatments but I thought if I tried it out and had a reaction then I could go back.
