Oh man, I had something like this happen to me as well. I got a message from my neurologist and didn't see it until office was closed. I was like no way am I going all night without knowing what he was calling about. I called the guy on call trying to get ahold of him. He said, I can't contact him as he is not on call. about 10 minutes later my neurologist called and it was something about the canceled MRI.
BTW: I thought this was going to be a post about you really almost pooping on yourself lol.
