Carrie Underwood is opening up about her scary fall.

In one of her first interviews since undergoing surgery for a broken right wrist and having 40 to 50 stitches in her face after tumbling outside of her home in Nashville, Tennessee, last November, the 35-year-old singer explains what led to the incident, and how she's been recovering.

"I fell down [and hurt] my right wrist," Underwood explains on Thursday's Bobby Bones show on iHeartRadio. "It set me back. The most frustrating part was trying to work out with a broken wrist. And just how much it can throw off your world, having an appendage that is there, but you just can't use it."

"I was just taking the dogs out to go pee-pee one last time and I just, I tripped," she continues. "And there was one step, and I went -- I didn't let go of the leashes, priorities! So, that's why my left hand's fine. But I went to catch myself and I just missed a step. If I had fallen anywhere else I would have been perfectly fine, but it was one step that messed everything up."

At the time, Underwood revealed to her fans that she may look a bit different after having to get stitches in her face. Host Bones told her that he couldn't see any difference in her facial features, and we couldn't agree more!

"I've been very fortunate in the healing process," the blond beauty, who is married to hockey star Mike Fisher, reveals. "I was lucky that when it happened, everything was kind of shutting down in the music world and we had the holidays and stuff like that. But I was at a point where I didn't know how things were going to end up. I didn't know what was going to go on and didn't know what it was going to heal like."

"[I fell] around my mouth," she adds. "You just don't know how things are going to heal or end up. It was important to me as I started resuming my life again and going to the grocery store and taking my kid [3-year-old son Isaiah] and stuff like that I was like, 'OK, someone is gonna creep on me at the grocery store.' And people are going to be like, 'What happened?' when they post it on Instagram."

Underwood continues on, explaining that her son was a little freaked out by it all at first, but "now he's sweet."

"For awhile I was worried he would be scared of me," she admits. "But now if I put makeup on, he's like, 'Mommy, your boo-boo's all gone.' I've got some plaster on right now, it's no big deal."

Underwood made her first public appearance since the fall over the weekend, performing "Cry Pretty" at the Academy of Country Music Awards. She admits that the return was a bit "nerve-wracking."

"There's just been a lot that's gone on in life in the past year," she says of her return. "It's always really nerve-wracking introducing new music, basically in that way, because the song came out just a couple days before the ACMs, so I was super nervous. I felt like I had never been on a stage before."

"We definitely wanted to keep everything music-focused," she adds, explaining why she didn't walk the red carpet. "I was going through lyrics in my head [like], 'Please, sing all the words right.'"

Underwood also stopped by SiriusXM The Highway's Storme Warren Show, on Thursday, where she talked about co-producing her new album, Cry Pretty, out Sept. 14. Previously with Arista Nashville, this marks Underwood's first release with Capitol Records Nashville, and her sixth studio album altogether since rising to fame after winning the fourth season of American Idol in 2005.

"I always feel like I've had incredible producers that definitely want my input. I mean, they want me to be happy, but they've always been willing to ... work with me," she recalls. "But I just kinda felt like it was my time to take some ownership and kinda be there for the grind in it."

"It's scary, to be honest," she continues. "You start writing and you're like, 'Man, if someone doesn't like this song, I wrote it!' Now it's this whole other liability, I guess."
