Lady Gaga tweeted on Tuesday that she would have to cancel the rest of her tour due to synovitis pain: “I hid it from my staff, I didn’t want to disappoint my amazing fans.

This issue could have very well stemmed from the activity of Gaga’s current tour, which includes more than 100 different shows worldwide.
