Replying to I need some assurance...

My dad just had (started about an hour ago) what seems to be a severe muscle spasm in his neck and just went to the hospital in an ambulance. My mom called the doctor and they said to call one for safe measures.
My dad's 48 so they're worried it could be a stroke or heart attack....

Has anything like this ever happened to anyone that anyone knows? I really hope it was just a bad spasm....


P.S. I hope all of your Christmas nights are going better than his (and my family's).
