Cassie,
I had headaches for 2 months straight, mostly tension headaches that were not too debilitating but none the less made me worry ever so much I had a brain tumor. The reason I thought this, was I too had the "off balance" which I still do get sometimes, and the kind of not being able to focus properly vision. I am the type of person that needs to see proof, so me and my doctor worked together to rule out a brain tumor, in fact he had to hold back the laughter when I told him that is what I thought I had.
These are the steps that he took:
1. Basic neurological exam(checking eyes(major give away here if you have a brain tumor), reflexes etc. In fact I had 3 seperate doctors do this exam(ER doc, family GP, another ER doc) all found nothing. Here is a really good website with what the exam tests for(almost anyone can do the exam)http://www.neurologychannel.com/neuroexam.shtml#mental
2. Xray of my sinuses. Came back totally clear.(A really good doctor will be able to tell almost right away by tapping your sinus areas with their fingers and if there is any pain, most likely you would have sinusitis, also if you lean forward and it feels like your face is falling off = sinusitis.
3. Eye exam by my eye doctor. Came back everything normal. Usually if you have a brain tumor your eye doctor can pick up that you have increased intracranial pressure.
4. MRI of head. Totally negative of tumors or other signs of neurological disorders like MS, etc.
5. An examination of my ear found that possibly had an inner ear virus which can damage the nerve that goes from the ear to the brain and cause almost unoticable hearing loss and feeling of off balance. I was given antibiotics although the doc did say that it would only help if it was a bacterial innner ear problem and not if it was a viral inner ear problem. The nerve was shown on the MRI to be normal.
As you can see my doctor was very reassuring and he told me before the tests he expects to find nothing wrong. He did say that he had read in mental health journals that anxiety can cause tension within the inner ear itself which can impede sensory impluses that travel on the nerve from the ear to the brain.
Also I good indicator that you do not have a brain tumor is that your heada
