The Foot - the Latest Theory

So our landlady comes over with her husband in tow to fix the leak in the bathroom. Such a multi-tasking husband she has. He's brain surgeon by day and a plumber on the side.
After fixing the leak, he demands to see Gene's foot! He wants to see the x-ray. "Ah ha!" he exclaims, when he sees the pin in his foot on the x-ray. Oh, that's just from when he broke his foot 20 years ago, we tell him. The good doctor insists that something is going on related to the pin and that it almost certainly needs to be removed. And in the meantime, he tells us to go to Ortopedia Alemana to get a plantilla a medida (insole thingee) to put in his shoe. We're thinking that this makes more sense than anything else we've heard so far. Why didn't the doctors at the hospital suggest this possibility, I wonder. Probably because we kept telling them that he had fallen. We were so convinced that the fall had started the whole thing that we convinced them of it!
