Miranda Lambert hated to disappoint her fans waiting to see her at Calgary Stampede on Thursday night, but when you make a living with your voice, you protect it. Lambert’s doctor told her she needed to let it rest, so she did.

“I am so sorry that I can’t be at Stampede this week, but I’ll be back in Calgary just as soon as I can for all of my Stampede fans,” Lambert said in a statement.

“We understand that this news is disappointing for fans,” says Paul Rosenberg, Chief Operating Officer. “We will know more about rescheduling the concert later; in the meantime, we hope that fans use their tickets for admission to Stampede and enjoy all that we have to offer- including live country music at Nashville North.”

Word then got out that Miranda Lambert is suffering from a serious inflammation in her vocal cords. It seems like so many singers are having this problem lately. Sam Smith is famously undergoing surgery to correct problems. Smith, Meghan Trainor, and Adele have all had to cancel shows due to vocal issues.

Meanwhile, Dave Grohl screams himself silly every night, and even plays on while having his leg and ankle braced. What gicves with all these vocal problems, like those Lambert has?

I can’t believe this is happening. Thanks for all your well wishes, I promise I'll do everything to get better soon! https://t.co/rKac66a2X2

When Sam Smith was forced to cancel tour dates in Australia and Japan, he later revealed that his vocal cords were hemorrhaging and he needed surgery. He has since gotten that surgery, but professionals warn that his voice will sound different.

“His voice will definitely change,” says Dr. Michelle Yagoda, a noted otalaryngologist.

Adele also suffered with vocal cord hemorrhage. And she had surgery, as well. Her voice appeared to make a full recovery, and she went on to perform live and record.

Will Miranda Lambert end up needing surgery?

There are no specific details available yet about Miranda Lambert’s situation, but the Mayo Clinic does offer some information about vocal cord inflammation, in general.

Vocal cord inflammation, such as that suffered by Miranda Lambert, is commonly called laryngitis. With this condition, “the voice sounds hoarse … in some cases almost undetectable.”

“Most cases of laryngitis are triggered by a temporary viral infection or vocal strain and aren’t serious. Persistent hoarseness can sometimes signal a more serious underlying medical condition.”

Fans have their fingers crossed that Miranda Lambert makes a full recovery. Maybe she should start chewing Dave Grohl’s brand of gum.

Just heard about your vocal chord inflamation! Get well soon bby @mirandalambert!!
