That’s when my muscles spasm. Everyone avoids change; muscles can’t abide it. Told to change, my muscles join the spinal rebellion, and soon my whole body is at war with itself.

Gil, my trainer, my friend, my surrogate father, explains it this way: Your body is saying it doesn’t want to do this anymore.

My body has been saying that for a long time, I tell Gil. Almost as long as I’ve been saying it.

Since January, however, my body has been shouting it. My body doesn’t want to retire—my body has already retired. My body has moved to Florida and bought a condo and white Sansabelts. So I’ve been negotiating with my body, asking it to come out of retirement for a few hours here, a few hours there. Much of this negotiation revolves around a cortisone shot that temporarily dulls the pain. Before the shot works, however, it causes its own torments.

I got one yesterday, so I could play tonight. It was the third shot this year, the thirteenth of my career, and by far the most alarming. The doctor, not my regular doctor, told me brusquely to assume the position. I stretched out on his table, face down, and his nurse yanked down my shorts. The doctor said he needed to get his seven-inch needle as close to the inflamed nerves as possible. But he couldn’t enter directly, because my herniated discs and bone spur were blocking the path. His attempts to circumvent them, to break the Club, sent me through the roof. First he inserted the needle. Then he positioned a big machine over my back to see how close the needle was to the nerves. He needed to get that needle almost flush against the nerves, he said, without actually touching. If it were to touch the nerves, even if it were to only nick the nerves, the pain would ruin me for the tournament. It could also be life-changing.
