Can Janet Jackson really rock with us again? After postponing several concerts due to health problems, the singer will reprise her Rock Witchu tour on Wednesday night at the Verizon Center in Washington, D.C., E! Online cited Janet Jackson’s manager as saying.

Moreover, the previously unrevealed illness the star suffers from is said to be vestibular migraine, which apparently forced Janet Jackson to reschedule nine shows up to now.

“After a thorough medical evaluation, it has been confirmed that Janet’s symptoms are being caused by a rare form of migraine called vestibular migraine or migraine-associated vertigo for which she is currently receiving treatment,” a statement released by the singer’s camp and acquired by E! News read.

Janet Jackson was transported to a hospital last month, after she fell ill during a sound check before a Montreal gig. Thus, she canceled the September 29 show, as well as several others and hasn’t performed ever since.

Kenneth Crear, the star’s manager, reportedly said that in spite of the fact that Janet Jackson wanted to return on stage as quickly as possible in order not to disappoint her admirers, she was unable to show up for the concerts due to her illness. He said that being a top performer can’t possibly allow Jackson to hit the stage without being in perfect shape.

“She’s a world-class entertainer and needs to be at the top of her game to give her fans the show they expect. She’s feeling much better and is ready to hit the road again to finish the tour,” E! Online quoted Kenneth Crear as saying.

Janet Jackson’s postponed shows in Montreal, Philadelphia, Boston, Greensboro, N.C., Atlanta, Fort Lauderdale, Fla., Uncasville, Conn., Verona, N.Y., and Manhattan will be rescheduled.
