is anyone struggling to breathe even if the peak flow doesn't drop much? My best is 550 on Symbicort plus Spiriva and I find that the peak flow doesn't drop below 470-500 even if I struggle to breathe with tight and burning chest?
Sometimes even with confirmed chest infection and wheeze across chest as per stethoscope my peak flow sits at 500.
Anyone else knows why? Is it asthma or likely something worse like copd?...
