The 23-year-old 'Bad Boys' hitmaker took to her Twitter page to tell fans she had "pulled" her shoulder, reported Contactmusic.
"I'm in so much pain. During a performance. Sleeping on it made it worse, then rehearsals killed it," Burke said.
The singer scheduled an appointment to see a physiotherapist but said that her concerts this weekend will still go ahead as planned.
In a follow-up post, she wrote, "(For) those asking, the shows I have this weekend won't be affected by this."
