 "Two and a half months ago, just before a show in Dallas, I lost most of my hearing,” Lewis said in a statement Friday. "I can't hear music well enough to sing. The lower frequencies distort violently making it impossible to find pitch.” 
  
 After seeing a variety of ear specialists, including the Mayo Clinic and the Stanford Ear Institute, doctors diagnosed Lewis with Meniere's disease, which can cause hearing loss, tinnitus and vertigo. Doctors also recommended that Lewis discontinue touring until the condition improved. 
  
 "Therefore the only prudent thing to do is cancel all future shows," Lewis wrote. "Needless to say, I feel horrible about this and wish to sincerely apologize to all the fans… I'm going to concentrate on getting better, and hope that one day soon I'll be able to perform again." 
  
 Lewis and the News had six shows scheduled for the spring and summer, including a gig at San Francisco's Outside Lands festival, and were also on board to open for Jimmy Buffett for a stretch of dates. 
  
 In 2011, Ryan Adams was forced to take a two-year hiatus from touring due to his own battle with Meniere's disease. "All of a sudden you start seeing double and then my hand starts shaking, and then it's like you're in an elevator and the bottom just drops out and your bones feel 1,000 pounds," Adams told Rolling Stone in 2014 of his symptoms.

 Huey Lewis & the News have canceled their remaining tour dates for the year due to Lewis' gradual hearing loss. 
  
 In a new statement from the band, it's revealed that Lewis -- who was scheduled to perform at Outside Lands this summer, in addition to a number of headlining shows throughout the country -- has lost "most" of his hearing, and that his doctors have indicated he suffers from Meniere's Disease, an inner ear disorder that can cause vertigo, tinnitus and ear pressure. 
  
 "Two and a half months ago, just before a show in Dallas, I lost most of my hearing," he writes. "Although I can still hear a little, one on one and on the phone, I can't hear music well enough to sing. The lower frequencies distort violently making it impossible to find pitch... The doctors believe I have Meniere's Disease and have agreed that I can't perform until I improve."

Huey Lewis has had to cancel the rest of his tour dates in 2018 for one of the worst of reasons as a musician: He's nearly deaf. In a statement, the singer says he "lost most of my hearing" a few months ago before a show in Dallas, and doctors think he has the inner ear disorder Meniere's disease, per Billboard. "Although I can still hear a little, one on one and on the phone, I can't hear music well enough to sing," writes Lewis, 67. "The lower frequencies distort violently making it impossible to find pitch." Lewis, however, says he hopes to improve and return to performing at some point. Rolling Stone notes that Ryan Adams had to take a two-year break from touring in 2011 after the same diagnosis of Meniere's disease. The disorder is a "somewhat mysterious condition" that often results from a viral infection, reports USA Today. Those suffering from it often have dizzy spells and severe vertigo, but it can be treated, especially if caught early.
