Greg Walker, who suffered life threatening seizures July 30 during batting practice, says he may start taking batting practice in another week and perhaps return to the Chicago White Sox for a few at-bats.

The first baseman on Wednesday held his first meeting with the press since the seizure, he wore dark glasses."Everybody tells me I look sleepy all the time, so I figured I might as well wear them," Walker said.

Walker walked slowly and talked groggily, the result of continued medication. But he said he feels better.

"Basically, how I feel is how well the medicine lets me feel," he said, adding that he is walking as part of his rehabilitation.

"The doctors have given me nothing to believe that this will end my life or baseball career," he said "A lot worse things happen to people. I feel lucky to be hear."

The doctors call Walker's condition cerebal vasculitis, or a swelling of the blood vessels in the head. What caused it is uncertain. But Walker has vivid memories of what happened while he was taking ground balls at first base before the game with the California Angels.

"I remember catching the ball," he said. "It felt like I had pinched a nerve in my right hip. I remember laughing for a second. In another second, my right leg was numb and in another second, I knew something serious was wrong. My first reaction was that I had had a heart attack."
