Possibly one for us older SP'ers.
Both my doctor and I are working hard on trying to find the source of a mild flue like illness that has been hitting me for a very long time now, (decades).
We are getting clues it is caused by some sort of inflammation that shows up in blood tests, and has caused what has been treated as Arthritis. Usually something that periodically starts with my right big toe, and then moves around my right foot, but sometimes hits my left foot, (as at present).
Anyway. Walkers feet.
In examining my feet the other day my doc took one look and said "Walkers Feet"! A number of bruised looking toe nails: they do fall off with regularity.
And tonight he had the results of a foot x-ray he had done to see if there was any clue as to what was causing the inflammation. There wasn't. But the report (in medical geek), led my doc to say, "They are telling us you do a lot of walking: there is some minor damage there because of the walking".
So I wonder if anyone else here has a similar "problem" with the impact of years of walking on their feet?
