After an acoustic neuroma, you have to train your brain about the changed input. It's used to getting balance info from both sides. One safe thing to do is jigsaw puzzles. You're turning your head and focusing repeatedly, but you're sitting. I used to break out in a sweat just doing it, but I made myself do it several times a day. The best thing is walking. Once you feel better, as you walk, turn your head to one side and focus as you walk, and then to the other side. Also do this looking up and down. Start off with someone with you, as it may get you off balance. I had to stop to turn and look for traffic. But walk, walk, walk. If it's just to the mailbox, OK. Gradually extend your walks. If you don't move in ways that make you dizzy, your brain won't learn, so don't avoid it. Just set your own pace. I had a chair in the shower. I'd sit on the floor to dry my hair, and then I was ready to go back to bed! Now (4 years) I can do whatever I want, including climbing climbing walls, riding on a sailboat, etc. Just hang in there.
