Frieda, I can't promise that it will help you, but taking antibiotics for chlamydia pneumoniae does help many and at the very least should stop further progression. There is plenty of information here, but you might care to write to my husband, Dr David Wheldon to ask his advice. In the meantime, here is a pdf which can easily be printed out and shown to people like your GP who might be willing to prescribe:

His email address can be found here, at the bottom of page one:

I will tell him you might be writing...............Sarah
