I picked up a serious lung infection/ bronchitis winter 11, loads of antibiotics, I was back riding Mar 12. Result – No
Jun 12 I felt a bit under the weather breathing was laboured/wheezy, back to the doctors, it turns out I had fluid on both lungs and was in a poorly way. Antibiotics a plenty, CAT scan, MRI Scan, bronchoscopy (camera down lungs), lung wash, more antibiotics and a year later back on the mend.
I have a work colleague, active out doors type, who after 15 months is still recovering from pneumonia.
And the moral of this story, respiratory aliments take a long time to clear up, no make that a very long time to clear up
Get your self an appointment with your asthma nurse, a peak flow meter and take it from there.
Best of luck with your recovery
