Has the cause of your bronchiectasis ever been investigated?
7 Years ago, after many months of bouts of bronchitis and one of pneumonia, a lung specialist diagnosed bronchiectasis caused by a severe deficiency of immunoglobulins (antibodies). Treatment consists of regularly replacing antibodies and has stopped my bronchiectasis from getting worse although I have needed frequent courses of antibiotics. Recent improvements in the way the treatment is administered have improved my health considerably and I have only needed a single course of antibiotics this year for a sinus infection.
I think I have been lucky that the lung specialist was quick to diagnose the cause of my bronchiectasis and the immunologists willing to support my expensive treatment.
Even if the cause of your bronchiectasis is not known, you should be able to access the right antibiotics. (It may be that the last lot of antibiotics you had weren't targetting the right bacteria if you are still not well). Does your GP have the facility for getting samples analysed quickly? I don't always have to see my GP, I keep sample pots and drop them off at the surgery at the first signs of an infection. Sometimes I get a phonecall to say there is a different antibiotic required and a prescription is ready. I set up this arrangement after discussing it with my GP.
I was still working when first diagnosed and desperate to carry on, so made a nuisance of myself with the medical profession. I'm glad I did. I have a fair idea of how tiring, debilitating and horrible the condition is. You really shouldn't put off going to your GP, there may be more help available.
