Hi, think it was three years ago I had pneumonia and I developed a chronic cough which my consultant said was asthma. I was given a blue and brown inhaler. Eventually the cough went away and when I had a review and I was asked when I needed the blue one, I never did.I'vet used the brown one but to be honest I forget and I'm not sure when it needs changing as I can't tell when it's run out. Last time I saw my GP for something else, she said I could 'tail off' using it. Recently I've had a cold and fever and developed a chesty cough. How do I know if it's just a virus or if they're asthma symptoms? I have never had any symptoms apart from chronic cough.
