hi, my friend was holding my new samsung galaxy camera, and I turned around, and she hit my lip with it by accident. my tooth hut aginst my lip when it happened and now its swollen, and it bled a little bit. but, I must have damaged some nerves because now the same side of my whole cheek is a little numb and feels wierd if i touch it. I'm freaking out a little. is the damage to my cheek permanent or just temporary and will heal in time..? please help? thank you
