It could be, anno. The asthma I get is of the exercise-induced/delayed reaction/infection-related sort. DD3 had a cold last week and she is very generous with her germs, so I have been fighting that infection off too.
I think that if I didn't have arthritis and what is a permanent sore/tender spot to the right of my sternum (possibly a result of arthritis itself), then common cold viruses, driving, swimming, scything, hedging (and almost all other aerobic exercise type activities) would be less of a problem. As it is, I think the fact that there is a constant mild inflammation there (I don't know if I'm using the term correctly; it's always sore there anyway and not on the other side, and I can remember first noticing this when I was revising in the school library for O-levels, leaning on the library table from a rather too low chair) means that anything that causes chest muscle use, including breathing more heavily than usual because of exercise, causes exacerbating symptoms in my lungs. I've read somewhere, more than once, that cartilage deterioration is not picked up on x-rays until it's really quite bad. Neither is asthma.
I always used to wonder, when hill-walking and such, why it was that I was more breathless than people who were not as fit as I was, and who were far less active as a rule. When I was teaching dancing I was very fit and could talk as well as dance but I did get short of breath. When other people clearly had much more breath left (so to speak) than I did, I used to think they just weren't putting as much effort in as I was. That was actually a reasonable explanation because I was a better dancer than most of them – not boasting, just the plain truth (a GP friend who was in my class said I was still a better dancer than other people even at 39 weeks' pregnant with DD3; good dancing is about body awareness, good balance and muscle control). At least, I thought it was a reasonable explanation until I was diagnosed with asthma in my forties. An lot of odd things then made sense: that's what had been holding me back! The only trouble was, because I had always been more active and fitter than most people, nobody but me realised I had been held back. I used to wonder why I couldn't swim faster, for instance – I was strong enough but didn't have the breathing capacity. Even when asthma is not actually bothering me, my lungs are about twenty-five percent less efficient than they should be. It's all very baffling. At least the medics are baffled too.
I do wonder if whatever exposure I had to TB, which made me immune, without my being aware of it, made a difference somewhere in my teens or earlier.
But who knows? Until the fundamental causes of diseases like asthma and arthritis are better understood, it's all speculation.
The weather is too nice to waste. I'm going out with a pair of secateurs and will do some gentle snipping before getting back to That Quilt
