His muscles are sore, his joints ache, he's fatigued and his skin is super-sensitive, the first U.S. astronaut to spend almost a year in space told reporters Friday.
"I'm kind of surprised how I do feel different physically than the last time, with regards to muscle soreness and joint pain," Scott Kelly, 52, said during his first press conference since returning to Earth after 340 days in orbit.

Then, there's what Kelly called "the skin issue."
"Because I hadn't touched anything for so long, (had) any significant contact, it's very, very sensitive, almost like a burning feeling wherever I sit or lie or walk," Kelly said.
Kelly and two Russian cosmonauts, including Mikhail Korneinko who was Kelly's crewmate through the year in space, landed in Kazakhstan late Tuesday.
Kelly, a veteran of three previous spaceflights, flew back to the Johnson Space Center in Houston the next day and immediately began a series of post-landing medical tests that will last about a year.
