I moved out of my last house in July. Since about February I had developed really bad, itchy eczema everywhere - all up my arms and legs and up my stomach and chest. It never stopped itching. (Not flea bites!) I also had a terrible dry cough, day and night. It was physically exhausting me to cough so much. Stupidly I didn't go to the doctor as I was afraid he'd tell me to get rid of my cats.
However, since moving to a new house, both these symptoms have almost immediately disappeared. I still have some itchy skin, but not nearly so much, and the cough has totally vanished.
So what on earth was causing these symptoms? My cats now go outside for most of the day, so perhaps they're not shedding so much indoors? Who knows?!
