You truly need to get a second opinion. You should have walked out of his office stating that he obviously doesn't care, or doesn't have the time for you. Sounds to me like you need a neurological work-up. Seek a second opinon, and don't stop until you get the answers you need and deserve.

Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is. However I will try to provide you with some useful information.
There are several causes of headaches. Headaches can be divided into primary and secondary. Primary headache disorders are headaches without a direct cause. These are diagnosed after secondary causes have been excluded. Secondary headache disorders are due to an underlying problem, there are many many causes but some include medication side effects, systemic illness, nervous system infection, tumors, bleeds in the brain or clots in the veins of the brain, and others.
It sounds like you have a headache associated with eye pain. This could be a primary headache disorder (a headache disorder without a direct cause). Primary headache disorders are much more common than secondary ones. Headaches that cause eye pain with headache include migraines, which usually a pulsating throbbing one-sided pain with nausea and discomfort in bright lights that lasts several hours. Another type is cluster headaches, which are sharp pains that occur around and behind the eye often at night and are associated with tearing of the eye and running of the nose. Another type of one-sided headache that may be associated with eye discomfort is called paroxysmal hemicrania. This is marked by episodes of stabbing or sharp pains that occur on one side of the head and may be associated with eye tearing or runny nose.
In addition, headaches associated with eye pain can be secondary, this can not be excluded without imaging of the brain. Without further information about your headache, it is difficult to provide you with adequate information. However, it is important for you to understand that if you have not experienced headaches in the past and you are now having new head pains, seeing a neurologist is a good idea if you are concerned that your neurologist has not given your symptoms enough attention, re-evaluation is warranted, just to make sure there is nothing serious causing this pain. Imaging of the brain and sometimes then neck (and sometimes the arteries and veins of the brain) is usually indicated depending on your exact symptoms, your physical examination, and other factors. If a specific cause is not found, then the neurologist can at least understand what type of headache you have and recommend specific therapy for it (certain medications can be very effective for the different types of primary headaches).
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
