Twitching middle finger on one hand

[frazzledmommy]

My daughter is 13 years old and has been bothered by her middle finger twitching. It happens several times a day for long periods of time.

She does have hypothyroidism that's treated with Levoxyl.

She's asked me what could be causing it and if she should see a dr. I don't know what to think. It seems like such a small thing, but it is very strange. Does this sort of random singular symptom warrant a dr's visit?
