I currently have a headache, feel lightheaded, nose pressure, have sore ears and eyes. what could be causing these symptoms?

Sinus infection?: Could be a sinus infection or even an infected upper tooth. I would not hesitate to see a doctor asap to get a thorough history and exam to determine how to treat the issue. Don't wait. Infections can spread quickly.

Anything: Your headaches could be coming from tension, dehydration, lack of sleep/poor sleep, skipping meals, stress, eye strain, teeth grinding, sleep apnea/snoring, or chronic sinus problems.
