I had a dreadful cough for years that wouldn't go away. It tended to be better in the summer months then worse in the winter, especialy, though not neccesariy after a respirarory infection. I was coughing so badly one day that a recently retired chest physician told me to get myself referred to the hospital and get my chest checked over immediately. I did but nothing was found. This was about 1985 before CPn was discovered to be a pathogen. I had already develped MS but then it was very mild RRMS. Later I develpoed adult onset asthma. Since starting th treatment, my asthma has gone and I don't cough hardly at all. I also used to get quite bad hayfever and sneeze a lot. The hayfever is now minimal and I have only sneezed twice tooday: it is now 19,00 in the UK.
I have never had any sort of rheumatic illness, but you can see from the two sites mentioned in your previous post:

that CPn is implicated in the development rheumatoid arthritis. Many people with MS who are being treated on the various regimes also have it.
