Five years ago, when I was at the 2010 SVPCA meeting in Cambridge, my knees were very painful. Walking was a trial, and going up and down the steps to the accommodation was pretty awful. I had no idea why my knees had started hurting, and neither did the doctor who I consulted. I also have no idea why they stopped hurting a little later. This whole episode makes no sense, given my generally good health.
A few months ago, the same thing happened, but this time to my left foot. Again the doctor said my join was inflamed but he didn’t know why. (It could have been worse: he could have said I was suffering from idiopathic arthralgia.) And again, it cleared up on its own after a few days.
Yesterday and today, my left knee is painful, and I can’t really bend that leg. It makes it hard to go up and down stairs.
Why is this happening to me?
I ask not in a spirit of complaint, but of inquiry. It seems wrong to me that doctors can’t tell me why it happens, nor what I should do to help it pass more quickly, nor (most important) what I should avoid doing to avoid a recurrence. Surely someone knows what’s going on in such cases?
Or is this more than ignorance? Has it been somehow determined that it’s theoretically impossible to know the cause, just as we can’t determine from four-postulate geometry whether the parallel postulate is true? In other words, is looking for a reason a fool’s errand?
Does anyone know if there’s any research on this kind of thing?
