Mary:
Your question is pertinent because it covers an issue I think the majority of AN surgical patients have to deal with. In my case, I suffered from fatigue before the diagnosis, surgery and radiation but I also feel as if I have less stamina, now. I assume that the presence of the AN and my brain furiously trying to compensate for the loss of the vestibular nerve function was a large part of my pre-diagnosis fatigue. Now, I attribute the trauma of the surgery and radiation along with my age (65) to be reasons for my - if not actual 'fatigue' - lack of stamina. I always get a good night's sleep (7 or 8 hours) and yet, I fall asleep in front of the TV quite often - sometimes before 9 p.m. Go figure.
Realistically, the majority of AN patients are middle aged and that is a time when your body starts showing signs of 'wear and tear', especially if one is not in excellent health, which few of us are. Then, you have a tumor that messes up your hearing or balance - or both, while your middle-aged brain frantically tries to adapt. We know AN surgery is hard on the body's resources. Your being anemic is certainly a major factor. Add to that, the sheer physical activity necessary to parent two very young children, do housework, etc and you have a sure-fire formula for fatigue. Of course, this is supposition on my part, not a medical opinion, but I believe it has merit. I don't have a solution for your fatigue but your doctor might have an idea. I would ask him (or her). I trust you'll feel stronger, soon.
