Do I have chronic tic disorder or mild tourette's, or are they the same?

Hard to say. To be a "Tourette" sufferer you would need to have a pattern of uncontrolled movement/events that fulfills the multiple pieces of this affliction.This includes vocal/throat/oral events as well as motor activity. Tourettes by definition are chronic, but you can have a chronic tic (>6mo) that is not Tourette.
TOURETTE'sSYSDROME. Is hereditary tic disorder that begins in childhood, therefore it is a chronic tic disorder.
