LADY GAGA can no longer walk, she confirms.
Gaga, 28, Tweeted the sad news as she canceled three upcoming gigs on her Born This Way tour.
"I've been hiding a show injury and chronic pain for some time now; over the past month it has worsened," Gaga explained via Twitter.
"I've been praying it would heal.
"I hid it from my staff. I didn't want to disappoint my amazing fans. However, after last night's performance I could not walk and I still can't."
Gaga said she had been diagnosed with a synovitis, a condition sometimes associated with arthritis and lupus, which makes joints tender, swollen, and difficult to move.
Gaga also regretted disappointing her fans.
