All right, let me go into more graphic detail for you. After the two days of abdominal cramping and what I thought was first food poisoning or a UTI, I went through about 20 hours of agony as my stone ground it's way through my lower kidney, and through my left ureter where it lodged itself at the bottom, just above my bladder. This is when I could finally move and went to the hospital, saw a urologist and had a cat scan. It was determined that there was not full blockage through the ureter, so my choices were, after waiting a few days and getting vicodin (placebo to me), if it didn't pass fully on it's own, they could pluck it out, or I could try to tough it out until it did pass. After a discussion with my father in law about the time they plucked his out, there was NO WAY in hell I was going to let them do that after suffering through this trauma. So my stone sat there, lodged inside me. The good news is that after a day or so I wasn't urinating pink lemonade anymore, but if you think I wasn't in any pain, allow me to wish such a thing upon you. And this went on...
...for over four weeks, where I ebbed and flowed between dealing with it, and the mental nightmare of having them remove it. Then, and only then did the stone finally fully pass.
I'll state once again. This had NO impact what so ever on allowing me to suffer greater pain on the bike, or XC skiing, or running, or anything else. None. Zero. Zip. Nada.
Now, for a corollary to "long term pain". I'd have to wonder why if it's simply a matter of pain, that after being shot and losing so much blood, Greg Lemond, after he came back and in 1991 in his own words finally felt like his old self, finished 13th in the Tour, and couldn't even finish the 1992 Tour, with his career over at 31. You'd think after being in so much pain for that long, he would have crushed everyone. Or is it cancer, and only cancer that makes you able to tolerate more pain on the bike?
As to Armstrong's size, here is a photo of him taken this year at the team's Canary Islands facility:
