One side of my face is fatter than the other?

One side of my face is rather than the other, it has been like this for a while now and I'm not sure why. When i take a picture from the iPhone camera is makes it obvious but if I take it from Instagram it looks fine, I'm not sure if anyone has this problem or rather it has something to do with the camera.

Does anyone know what it could be or why one side is fatter this the other?

Does anyone know what it could be or why one side is fatter this the other? Possibilities:
1. You actually have a non-symmetrical face.

2. You are seeing perspective distortion which happens when you take pictures at arms length. When the camera is closer to the subject, perspective distortion becomes worse. When you snap your pictures, are you using the same hand for both shots? If so this will cause the camera to be closer when taking a shot on the opposite side of your face relative to your hand holding the camera.
Perspective distortion is why selfies usually look bad! Better to have the camera at least 5 feet from the subject.

3. Lighting. Lighting angles can make features look fatter or thinner. Lighting is something portrait photographers use in their arsenal of techniques to make their subjects look their best. There are medical conditions that can cause that. Schedule an appointment with your school nurse.
