John Mayer underwent surgery this week to remove a granuloma from just above his vocal cord, the singer announced on his blog.
Mayer said the surgery was necessary after his attempts to rest his voice didn't help.
Mayer announced the ailment last month and pushed back the release of his new album until 2012.
