Brief Answer:
Stress could play a role.

Detailed Answer:
I read your question carefully and I understand your concern.

Since the issue has been constant over several months without new symptoms I do not think have to be scared, threatening issues such as tumors, stroke, brain infections etc would have produced other symptoms in the meantime.

Whether it could be related to stress...yes it can play a role. Tension type headache is the most common type of primary headache (primary meaning without an identifiable cause) and it is often triggered or exacerbated by stress and anxiety. The trembling would be in the favor of such a hypothesis. Ibuprofen (Advil) is usually more effective in relieving it than Tylenol.

Of course it would be prudent to consult your primary physician to be examined for possibility of ear infection or other signs you might have missed, but as I said no indication of an alarming issue.

I remain at your disposal for other questions.
