Fasciculations?

I should've never said it was going to be a long day....Averie started having a weird muscle spasm/seizure in her right shoulder and chest. She was completely coherent the whole time, but we ended up at the ER because I have NEVER seen something like this and no idea what to do. She was wide awake so I didn't think it required a diastat, but it was concerning enough I wanted her checked out. They couldn't tell if it was seizure activity or something called muscle fasciculations. All her vitals were normal and she wasnt acting like it really bothered her(she was cracking jokes and actually being the most normal I've seen her in weeks!) but she was clearly uncomfortable enough that she couldn't sleep and it kept starting and stopping so we ended up giving her oral valium and she finally fell asleep around 3am...it stopped not long after that. Now this morning she's sound asleep and the thing is stopping and starting randomly. What to do...hoping it stops and we can avoid a trip back to the hospital. ....fasciculations....really?  At least its an interesting word to say....
