Hi, Jake. Welcome aboard!I have just read the article you mentioned and found it alarmist and misleading. FD is very poorly understood by the medical world who 'think' it is neurological and then experiment blindly on poor, desperate musicians who just want to play again. They say it is incurable, but that is only because they have failed to cure anyone using crazy things like Botox etc.
My advice would be to go to

...and watch his interviews with a man called Joaquin Fabra who has been successfully rehabilitating all types of musicians for over 20 years. The musical world's best kept secret!
Stay positive!
