I used to be a big smoker and doctors told me, at the time, that I had asthma. I was on two inhalers but when i stopped smoking, my asthma cleared up and i haven't needed an inhaler for maybe 9 years.
However, I have discovered that, at least three runs, when i haven't even been badly out of breath, I've had a slight burning in my lungs and started coughing. I did wonder if it could be pollen but on at least one of the runs i was down by the sea and away from any sources of pollen.
Has anyone had a similar thing happen whether you have asthma or not?
