I was diagnosed with asthma 25+ years ago, which had always been well controlled, other than when I got a chest infection after a cold. Last summer, I started waking up at night struggling to breathe/talk at the same time and after this returned after a course of antibiotics and oral steroids, was given Symbicort by my GP. All has been good until now when I have a chest infection, so am back to waking up breathless, am out of breath most of the time and have a sharp pain in my back, and Salbutamol is only working for about an hour. However, despite this, I never seem to get any wheezing, so always feel like a bit of a fraud in terms of asthma if I visit the GP, as they can't hear any when they listen to my chest - is this normal?
