Stevie Nicks, an American singer best known for her work with the band Fleetwood Mac, has offered more details on her recent health scare and sudden postponement of two concerts earlier this month. Ms. Nicks’s show was originally scheduled for July 6, but Glasgow’s venue OVO Hydro canceled the gig just a few hours before the singer was set to go on stage explaining she needed “a minor surgical procedure” on her leg.

At her rescheduled show on July 24, however, Ms. Nicks revealed that it was actually an infection that required emergency treatment. It is not known what exact kind of infection the singer suffered from.

“When I got here, I was just really so excited to be in Glasgow. And then I don’t know what happened, I just got this weird infection, and it just went crazy,” she said. “And I’m staying at this fabulous castle .
