It's been a week since Jennifer Grey won the Mirror Ball trophy on Dancing with the Stars, so how does she feel now? Not great, actually. Well, at least physically.

"I have this nerve that is squeezed between the bones in my foot called a neuroma that's gotta be dealt with. I got tendonitis in my left knee when I was doing the Argentine Tango, all the deep squats and lunges," she told Extra at the opening of Disney Times Square.

But the big surprise is that Jennifer almost wasn't able to compete in the finale. "The night before, when I did the freestyle, I ruptured a disc in my back. I went to the hospital the morning of the last show, and they gave me a shot of cortisone to get me through it — that should last a couple weeks. I'm about a week into that shot... I think I'm going home to do surgery this week to take care of that. Pain has become my friend." Ouch!

Still it wasn't all "pain," as Jennifer loved competing and the fan interest. "I loved that so many people got obsessed with voting and became active instead of just having their favorites and not taking any action." Grey also has a soft spot for second runner-up, Bristol Palin. "The fact is, she's just a great girl that just turned 20, who has never been in the public eye like this and has never done anything physical like this. It was so hard what she was doing — and so hard what I was doing. Everyone was struggling — you can't help but root for everyone!"
