Eclipse,
I’m not a doctor, but from personal experience, ear/jaw/tooth pain can have a wide variety of causes, including and not limited to:
– Pain from clenching or grinding teeth (a night guard might solve the problem).
– Ear infection(s) from your recent illness.
– Wisdom tooth infection.
– Sinus pain/congestion.
– Root canal problem.
At any rate, it’s a good idea to see your doctor and/or dentist! It’s especially important not to sit on a root canal problem, since those can become excruciating.
