Results just back (comfortably before sqad's prediction of 'Christmas') - "no lesions or evidence of any other lung or heart problems".
Which does still leave the "Why the **** am I coughing so much" question.
GP thinks that it's not an infection (been going on too long without either getting better or going critical) - so first idea is to break the cycle of inflammation with some high dose steroids for a few days.
All in all, though, I'm a lot less worried than I was an hour ago :+)
