Katek I'm so gad that your X-Ray result was good. Having had the same type of wracking cough twice during the past three years I know how debilitating and exhausting it can be.
Being a fairly compulsive Googler of things that are new to me I looked up atopic personality and I am dumbfounded to find that one of the studies on this describes me and some of my physical health problems to a T! 
I had never thought of myself as having a personality 'system' and still less that my personality could/would influence this particular aspect of my health, but having read this hospital study I recognised myself so clearly that I'm now off to do some further Googling.
