Weird thing happened what was it?

So I had this weird attack thing happen. Two days before I was extremely moody and emotional, much like PMS, but it wasn't PMS. I was also sort of twitchy. The next day was pretty much the same except the twitching got worst. Then on the day of the "attack" my I was extremely twitchy and jerky and. very tired my head hurt and my muscles were in a lot of pain. I have been to a doctor about this and he has seen some of this himself, and he has forwarded me to a neurologist who specializes in movement disorders. I have had twitching for a while, but never with a mood change like this What could be causing this?
