DUBLIN (Reuters) – Irish-American dance master Michael Flatley is back on stage after years of suffering from a "mystery virus," thanks to a treatment by an Irish "energy healer," Irish media quoted Flatley as saying on Wednesday.

Flatley, born in the United States in 1958 of Irish heritage, rose to fame as a member of the "Riverdance" troupe that helped propel Irish dancing into the global spotlight and later opened his own "Lord of the Dance" show.

He was taken to hospital in London in 2006 with a virus that forced him to cancel the European tour of his "Celtic Tiger" show, a dramatisation of Ireland's history.
