Kenneth -
hi and welcome. I'm glad you found us. There are lots of us here who will help you not feel alone anymore. And, no, you are NOT a whoose (or however you spell it!)
While not all AN patients have exactly the same symptoms, the balance issues, headaches, facial pain, and tinnitus you are experiencing seem to be common ones. The panic attacks and the trouble sleeping are probably more related to stress and anxiety than the actual tumor.
I don't know how realistic it is to call in sick for 4 weeks until you have surgery, because you will be calling in sick for 4 to 6 weeks post op. I would imagine your employer would not be too happy with that situation and in addition it might make a difficult financial situation for you. Perhaps you should talk to your doctor to see what he can give you to alleviate your symptoms.
The professor who told you ANs typically don't grow after discovery is incorrect. ANs can and do grow, but they typically grow very slowly. In fact, sometimes patients are able to watch and wait for an extended period of time; possibly even years.
It doesn't sound like the military doctor, the ENT, or the professor gave you any factual information on ANs. The ANA has some excellent literature that explains what ANs are, their treatment, the related side-effects, etc. Although you said surgery is your only treatment option, you might like to read this literature. I suggest you contact the ANA and ask them for it.
Good luck, and don't be a stranger,
Jan
