14 y/o daughter started having quite obvious tremors today. She has complained of sudden weakness before, but we've never observed it.

There seem to be three different ones: rapid shaking of head while flapping right arm at the elbow, and the second looks like a shiver is running up her spine (neck tenses and shakes at shoulders); third one is rapid scratching of right side of head with right hand. She doesn't seem distressed, no confusion, headaches, slurred/disordered speech or anything of the like.

We would have to go through our GP to get a referral to Neuro but our GP in isn't great in so it would be nice if we had something to suggest as a possible diagnosis in case the tremors are transient and don't appear during the doctor visit. Thoughts?
