I've had times where I couldn't tell if it was a migraine or the flu either. I get a lot of migraine syptoms without the headache, and sometimes headaches that are not migraines. Hopefully someday they will figure things out.

I was thinking about it last night, and I get some shocks in my fingers sometimes. I attributed that to playing an instrument for people with long fingers when mine are short so I had to stretch them and maybe stretched them too much. That was over 20 now so I don't think that's still the case. My fingers are also where I get the twitches so it kind of makes sense.

It makes me feel better knowing that I'm not alone in this.
