I'm Having Bad Pain In My Upper Left Jaw/cheekbone Area.

I'm having bad pain in my upper left jaw/cheekbone area. It's severe in the mornings and then more moderate in the afternoons and evenings. I haven't had any kind of injury or trauma in that area, so I'm not sure what caused it, but it hurts very badly and makes eating, talking and yawning difficult. I've had for over a week now. Do you have any idea what I can do to help it go away? IBprofun and Advil aren't doing much to help.
