okay so i don't know if this could be tourette's or not or something else. basically, everyday (i'd say at least 3 times a day) i get this all of a sudden jerks in my body. it's not like a seizure, it's just one big jerk of my whole body. maybe it's just like a burst of energy, but it happens a lot, even after i've just been using a lot of energy. whenever my mom sees it, she just things i'm cold, like a shiver, but i'm not. is this normal? does it happen to anyone here? one of my friends always sees it and laughs.
