Barack Obama, back in his home town after a tour of Afghanistan, the Middle East and Europe, saw a doctor at the University of Chicago Medical Center on Sunday night to deal with a sore hip.
"His hip has been sore from basketball for a few weeks, so he's going to see an orthopedic doctor," Obama spokesman Robert Gibbs said.
As he left the hospital, Obama told reporters: "I had small X-rays. Everything's OK. I think I'm going to be good in about a week."
Obama is a lifelong basketball player, and he squeezes in a game every now and then on the campaign trail. At one stop during his overseas trip, he shot baskets with U.S. troops in Afghanistan.
