It's not an eye twitch, but sometimes I get this chill over me and my body just like jerks, just once though from my stomach up, I don't know what it is. It's kind of uncomfortable. usually i move my neck to the side, its really embarrassing actually =[ i havent always had it, is it normal for your body to twitch?
Dont feel discouraged about your chills theyre perfectly normal (from what i read) ^^ But if you're worried, go and see your doctor :)
take care
