Heather has been feeling sick lately with a stuffy nose and thick, yellowish mucus. She thinks she has a cold as she's been coughing and feeling tired and achy in the upper jaw and teeth. The over-the-counter medicines she's been taking to relieve such symptoms are not helping at all though. In fact, she has recently developed a terrible headache. Feeling helpless, she made an appointment with her family physician. After learning Heather's history of symptoms and examining her face thoroughly, the physician asked if her headache worsened with light exposure or loud noises. Heather responded "No." What was the physician's likely diagnosis?
