I didn't do the front chin, only the square jaw,
 but one side of my lower lip and a little bit below it are tingling as if I've been anesthetized. I keep feeling numb, like when I get a cramp. It's
 not like I don't have any sensation at all, but I can't really feel it when I touch it lightly,
 and other parts . There's nothing wrong with it, but only that part is like
 that. Because of this, if you shape your lips into a right shape, it won't move as if that part is paralyzed,
 so your mouth will become crooked. Even when you brush your teeth, that side of your lip won't close, so you have to hold it with your hand when rinsing your mouth.
 The nerve damage is caused by it. It's very stressful.
 Is there anyone who had the same experience and was okay? How much should I have?
