Nobody knows Jordin Sparks' throat like she does, which is why the American Idol sixth-season champ said she found it laughable when reports surfaced last week that she had suffered a career-threatening vocal injury.

"I laughed when I saw [those reports]. They were saying I would never sing again, and I knew I could because, well, it's my throat," Sparks told MTV News in a Friday email. "My career COULD HAVE BEEN in jeopardy if I hadn't done anything about it. But I knew something was wrong and that I needed to get it checked out."

The 18-year-old was forced to cancel several of her recent performances after suffering an "acute vocal chord hemorrhage" -- a diagnosis that Sparks confirmed in her email.

"[The reports about the hemorrhage] were actually true," she told MTV News in the email. "My left vocal cord was bleeding, and I knew I had to get it checked and take care of it. I got back from the doctor yesterday and it's almost all the way healed. I'm gonna take a couple more days just to be safe. I should be back on tour in a few more days!! I'll be alive and kicking... and who knows, maybe my voice will be better than it was before!"

Prior to canceling her April 20 performance at Penn States's Bryce Jordan Center, Sparks said she was "struggling" to sing and was scared about the severity of her injury. 

"I've strained [my vocal cords] before, but people everyday do that. But I got to the point where it actually felt like there was a block on my voice and it wouldn't reach any higher," Sparks wrote. "I knew something was seriously wrong when I tried to rehearse and my voice wouldn't work. THAT was scary. I've never dealt with this type of injury before; I could literally feel the difference."

While she's currently "feeling good," Sparks added it's been difficult not using the talent that helped her win Idol.

"I'm supposed to be on full vocal rest, which means no talking, laughing, giggling, and singing," wrote Sparks.  "Can I tell you how hard that is!? I want to tell my fans: Thank you for all the prayers and your concern. You guys are what keep me going, honestly. But not to worry! I'll be better in no time!"
