My dystonia triggers

Bright lights (especially fluorescent lights)

Flashing lights

Loud noises (particularly high pitched)

Being startled

Stress

Doing too many activities (moving about, doing tasks in general)

The high pitched whining of a dentist's drill (which is why knowing a dystonia-friendly dentist is so important)

Temperature extremes

Excess visual stimulation

Loud bass music

Being sick

Wal-Mart - All the activity with shoppers or overhead music, announcments

more Fatigue than usual

Certain positions also trigger it, like turning my head too far to the left or right, or up and down, can start an attack.
