Over the last ten days I have become more and more breathless. I do not appear to have an infection as sputum is clear. I am on symbicort 400/12 and Ventolin. During the summer despite having an awful lot of stress, I was coping and not dreadfully breathless. I do not like to pester my COPD nurse as I obviously do not have an infection. My inhalers at the moment are utterly useless. Any ideas!!!
