This is a tough call. I see that your surgery was fairly recent. Your stats are similar to mine: translab, left-side, 100% hearing loss, large tumor, balance issues, fatigue, etc...I can tell you from direct experience that recovery from AN surgery can be very long and even at best you're never quite the same as you were before going into it. You're still on the early side of your recovery and some of these problems will improve over time. In my case you can add-on chronic double vision and heightened anxiety or nerviness. I've become very "short" with people since my surgeries (and oftentimes for very good reasons. I just don't put up with it like I used to).
There was a guy I met here through the forum years ago. He had a 3 cm growth and he had the same surgeons I had at the same hospital. We kept in touch off the forum because he lived close-by. Although his condition was not as severe as mine had been (I was plagued with hydrocephalus and shunt surgeries as well), he came through his surgery in much worse condition than I had; the worst of it being that he was afflicted with crippling headaches. I remember him saying to me that if he knew that he would end-up feeling the way had he'd never would have opted for surgery. Those bad headaches seemed to worsen and continued-on for a couple of years after his treatment. Then one day they just stopped and for no apparent reason.
Nerve cells are unlike other cells in that they do not reproduce. Unless they can be grafted together if they are cut there is no hope of recovery. If they are moved or even touched they can wreak havoc in the effected area of the body for years after. Over time they can reactivate or right themselves. This is why in the medical profession nerves that are tampered with are referred to as being "insulted". I believe the condition of either growing into or out of headaches can occur in AN patients after surgery as the body heals and the nerves shift and right themselves. Nerve cells are ultra-temperamental things.
I remember reading somewhere that many reported miracle cures were neurological in nature. Given the quirky, on or off nature of neurons, I thought that was an interesting observation.
All I can suggest is, barring getting on SSDIâ€”which can take years and is not realistic at this point for youâ€”try to wait it out. You may look into Imitrex which has proven itself as the most effective non-narcotic pain med for headaches:http://www.migraines.org/treatment/proitrxn.htm
For fatigue, combat it by eating properly and strengthening your body by doing whatever exercise you can manage to get in. This is crucial for anyone: proper diet + exercise = longer, quality living.
As far as the medical goose chase your doctors are sending you on, keep in mind that doctors are not perfect either. There are good doctors, not-so-good doctors and bad doctors as there are good and bad in any profession. I could cite one example after another of wrong diagnoses and malpractice. I was very fortunate to be living in an area with top hospitals, medical schools and some of the best doctors in the world: Boston.
Good luck with everything!
