Break the Matrix

Hi,
I'm new to face pulling.  I started a few days ago to try and improve my receded face after extraction orthodontics as a teen (and my face was pretty bad before then! ). I've been biting down on a doubled-up ribbon, rather than a belt, so that I could keep the teeth in contact. 

Initially, I felt aches in the back of my neck.  But now I get random aches in my forehead, especially where I have a few dents which I got from one or two knocks, as a child.  No pressure feelings in my cheekbones yet, so I'm wondering if I'm doing it right?...Not sure if you pull vertically with your arms up by the sides of your ears, or upwards but diagonally? 

Also, I think this has caused some facial lengthening, somehow....I've always had a tiny bit of sclera showing under my left iris, but now I'm getting a bit under my right, as well.   Please, can anyone tell me what might be going on??

I dont know what to tell you, maybe youre mouth breathing.

Just keep on doing it and mew, make sure your mouth is closed while you are sleeping, doung this loosens the bones.
