I struggle to breathe sometimes when I'm running; my chest is congested and my legs feel like lead. I've been prescribed a salbutamol inhaler to use before a run, but sometimes it doesn't really help. Other times, like very early morning, it's a lot better.
So the asthma nurse tested my peak flow this morning, and it was abysmal, well below 200, which is apparently pretty bad. She made a second appointment for this afternoon with the intention of administering more tests, which would take some time. The intention was to then probably prescribe a type of drug used for asthma in sports.
After the second of several tests, she looked at the results and said, with considerable surprise that my readings were above normal (as in very good) by quite a bit. Conclusion, it's something in the house I'm allergic to, and walking round Oxford for hours had cleared my chest and opened my airways.
The culprit is almost certainly our collie/arctic dog. The reason I'm better with a very early morning run is that he doesn't come upstairs, (though the cats and the other dog do), so I'm going out of the house before I've breathed much of his allergens into my system.
Conclusion, I'm not asthmatic. Advice: clip the dog and run early mornings. Not sure what his daddy will say to his darling boy having his posh pants and ruff removed.
But it's a relief to find out my breathing is normal when not exposed to allergens.
