Hey everyone. Thanks for the concern. No, I haven't been to a doctor. I crashed at 02:00 - at 04:00 I woke up. I think I rolled onto that side or something. I tried to crash again but gave up at 04:44 (memorable time) and ended up getting up and watching some TV and some of the Animatrix extras before heading into work for 08:00. The spasms seem to have stopped. I have a slight crick, and the muscle is achy, but the bad pain stopped. So unless it starts again, I think things are OK. I'm just a bit tired.
