I was afraid I would die too, at first, and if Sharon Osbourne didn't know the details about MS she might have felt the same way about her son. There are extremely rare cases that result in fairly rapid death. My bet is that's what she read and she was terrified. The people criticizing her are being unfair. If my son had MS I'd be terrified too until I was relieved that he would be treatable and hopefully have a non-aggressive disease course.
