Melissa Gilbert is back on the dance floor. After being rushed to the hospital during Monday's edition of "Dancing with the Stars," the former "Little House on the Prarie" star returned to rehersals Wednesday afternoon and joked about her injury on Twitter.

"Nobody puts Halfpint in the corner!" she tweeted to her actor friend Craig Bierko, referencing her character's nickname from "Little House on the Prairie."

Later, she tweeted that she was "very happy" to be back dancing with professional partner Maksim Chmerkovkiy.

Gilbert and Chmerkovskiy hurt themselves on Monday following an aggressive paso doble. Chmerkovskiy injured his elbow and pulled his groin; Gilbert suffered a mild concussion and whiplash and was taken to the hospital after feeling dizzy and nauseous backstage.

Gilbert was well enough to watch the show Tuesday night. In response to Sherri Shepherd's elimination, she  tweeted that she was "truly stunned." "If they can go any of us is fair game!" she added. "This makes my head hurt even more…"

Following Tuesday's show, Chmerkovskiy told reporters that Gilbert remains "in pain. She's got a big headache."
