Someone in another post or forum had written years back about their child starting a movement to relieve discomfort ... but then not being able to stop doing that movement.
For example, an allergic kid would clear his throat due to post nasal drip, but then keep doing it for weeks or months out of habit. Or scrunching a nose from having a cold, but then not being able to stop. Or sweeping the head to the side to get long hair out of the face, and even after haircut not being able to stop doing that movement.
Also just merely suggesting a tic to the child makes them want to do it more. (Mine says this all the time, does this mean it has OCD derivation?) Are OCD kids of tics treated differently?
Are tics, just tics - maybe from different origins, but all considered the same sort of thing?
