Singer/songwriter John Mayer has been diagnosed with granuloma, or an inflamed nodule near his vocal cords, he personally announced over the weekend.

"After several months of going week to week monitoring and hoping to correct the condition, I am sadly forced to cancel my upcoming singing engagements due to something next to my vocal cords," Mayer told his fans.

Mayer's upcoming album, Born and Raised, has been delayed.

Maybe he can also get a haircut in his downtime. Just kidding. Sort of.

"Until then I'll be spending time writing and composing more music and kicking an empty soup can around the West Village," the singer added.

Best of luck with that and get well soon, man.
