I also suffer with COPD and asthma and was diagnosed with pseudomonas a few years ago, my GP hit it with everything he could at the time and it appeared to have gone. Unfortunately this was not the case it just laid dormant and twelve months ago it reappeared, By then I had moved home and my new GP tried lots of antibiotics which would calm it for a week or so and then a new infection would start.
The inevitable repeated dashes to hospital and two week stays followed,until the Consultant diagnosed pseudomonas and tried several types of IV antibiotics but in the end admitted that this bug is almost un-killable.
I have been using Colomycin through a nebuliser twice a day since my discharge in November. Although I picked up another totally different infection I feel there is a definite improvement, I able to breath through panic attacks(which have reduced dramatically) and know that I have more control, but twelve months of infections and stays in hospital have left me very weak, just have to remember to take it slowly and not do anything silly. Just waiting for an appointment with Rehab, the last two appointment clashed with being in hospital.
A final word, mould. Our washing machine sprung a small leak and soaked under the laminate flooring, black mould formed, the result was while in the house breathing was very difficult once outside it improved. After one really bad attack and a stay in hospital a Doctor suggested that we check out the house to find what was causing the reaction, this time it was easy on return from hospital we could smell it, once the laminate was gone and the floor sealed I was able to breath and my wife's cough that had been there for weeks also stopped almost overnight. The fortunate part was the insurance company paid for the new floor and for the sealing.
