Blimey, where to start...
Well you've got the thin end of it for sure. And I'm very sorry to hear it.
I am surprised that you were massively treated for haemophilus influenza. It's one of my frequent fliers and I know the little bugger well. Often resistant to penicillin but usually sensitive to co-amoxiclav and - as far as I know - always sensitive to the flouro-quinolones like ciprofloxacin or moxifloxicin. A week and it's done.
What bugs to you tend to grow? If you're not sure, ask your doctors receptionist to print them out. Just say it's for your consultant and they'll usually be fine with that.
Getting aspergillosis is a bit of a bind, but steroid inhaler should keep it under control. The relvar should sort you out nicely there.
I have a little sympathy for the doctor - if he can't hear the typical sounds of lower lung infection he may, with some justification, feel that is likely to be a virus. Therefore no antibiotics.
However, the way to be sure is a sputum sample. And you should persist even if the first sample shows nothing. If you're still unwell a few weeks later, do or again . Sputum sample microbiological tests can miss a bug 20% of the time.
Consultant: if you have Bx (by the way 'mild' just refers to the damage they can see in the ct scan, not the frequency of infections or anything else) you need a respiratory consultant who knows what they're doing. There are specialist teams at the Royal Brompton in London, at Papworth in Cambridge (i think Rachel is with them). Where do you live - someone here will know a decent consultant and you can use NHS Choice to go to them.
Also, if you don't mind answering, how old are you? With age and height you can work out what your peak flow should look like and then what is a trigger level for action.
Your point in your last paragraph is the key one - an action plan. We don't get cured, we manage Bx. Hence the barrage of instructions in these responses.
And the primary objective is to break the vicious cycle of infection -> damage -> inflammation -> mucus -> infection. So don't tough it out, get all informed patient on your GP, tell him what for, hand in the samples, take the antibiotics (given the protocol mentioned above), get a specialist consultant.
For information, a good place to start is to Google 'bronchiectasis chest heart stroke Scotland'. Very very good pamphlet. It's the second result at the moment, and is at chss dot org.
Good luck
