I've had a cough for 12 weeks. It started off worse at night and I was waking up hot and sweaty,as well as bringing up yellow muscus. I was prescribed a 7 day course of antibiotics and given a chest x-ray as my doctor said one of my lungs sounded dull. The x-ray didn't show anything unusual. The cough got a little better but still lingered for a few weeks, though I was no longer bringing anything up. It got worse (I wasn't going 10 minutes without coughing) and I started bringing stuff up again so went back to my doctor who prescribed me a 10 day course of ciprofluxin (spelling may be incorrect), he asked me to come back in 3 days. I went back and he said the antibiotics should have had more of an effect and prescribed me a brown inhaler. It had got a lot better but is still here. Have had the inhaler just over two weeks, don't know whether to go back to the doctor. I am now getting a raspy/rattly noise in my chest occasionally, I also cough every time I use the inhaler.
