Headaches, Dizziness, Fatigue symptoms of ...?

In most cases headache pain, even severe headache pain, isn't the result of any underlying disease. In fact, the vast majority of headaches are primary headaches, headaches that aren't caused by a specific medical condition.

Where is the pain located?
What its character or type?
For how long the headache attack lasts?
Is this pain strikes quickly, usually without warning?

Sounds like it could be a hearing/ear or middle ear associated problem. I have a condition call cholesteatoma, the common symptoms are headache, vertigo and nausea, are just a few. I hope this hasn't come back to late, I just registered as a member. Your symptoms sound similar to what i experience.

I get these headaches every day and they last several hours. Sometimes several times a day. My whole head hurts.

This sounds very familiar to what I've been dealing with for the past few weeks (most recent bout). Vertigo/Dizziness are at the top of the list of symptoms, followed by headache (almost constant), sore neck/upper back, random aches & pains, and fatigue. I was told by my doctor on Friday that it's the flu- but I have a hard time believing it. I've been taking care of myself and the symptoms have not improved over almost 2 weeks.
Today I began to wonder if perhaps my neck/back pain isn't necessarily a symptoms but perhaps the cause? I had a moderate neck injury when I was younger, and perhaps my bad posture (sitting at a desk all day, sitting at a computer all night, sleeping with my head elevated) has come back to rear it's ugly head? Just another suggestion.
I don't know for sure- all I know is I feel your pain.
