In the link to the other interview with her (forget which forum.. Rumours?) she says initially it's "minor" and that she gets a shot of cortisone and poof! it's all good again. But by the end of the article she's saying what she says in this one, that it's limiting her ability to play, and even sitting at the piano isn't great. So..... does sound like for a big check she would get the cortisone shot and mime to pre recorded tracks...
