"It's just that I really don't want to know," Medlen said. "I want to focus on positive things and I don't want to put any pressure on myself knowing about those things.
"I could cheat and go look at the sheet because it's all mapped out through March. I just don't want to. I literally am taking this [rehab] one day at a time. I show up every day and find out what I have to do that day and that's it."
Medlen likely won't pitch competitively until mid-April in a Minor League rehab assignment. The Royals also have indicated he most likely wouldn't be available at the big league level until the season's second half.
"The funny thing is, I was ready to do a bullpen session right before I signed with the Royals," Medlen said. "They just thought it was best that we take it a lot slower, which is fine with me."
The Royals believed Medlen's rehab had to be slowed down because it was his second Tommy John surgery in four years.
"I'm totally confident in their plan for me," Medlen said.
Medlen, who signed a two-year deal with the Royals, simply is excited to have another opportunity to pitch. He still isn't sure why his first Tommy John surgery didn't resolve his elbow issues.
"I really don't know," he said. "I wish I had the answers. I wish there was clarity.
"There have been problems with my left hip and that's the one you drive with and drive against. So we've been trying to strengthen that. That could have been the problem.
"But right now, my whole arm feels really good. It feels like I have some snap on the ball. I even had a nice little burn in there, a good burn, like after you've had a good workout. I like it."
