Exercising and getting in the best shape possible before surgery is a good idea. It reieves stress before surgery and can only help after surgery. I did the same thing and I'm sure many others did too. In my opinion, it's a very positive thing to do. The fact that you are as dizzy as you are prior to surgery may be a good thing. My doc told me before I had surgery, the more problems I had with my balance prior to my surgery, the fewer I was likely to have afterwards. Once the damaged vestibular nerve is cut your brain stops getting those mixed messages and things will start to improve. I had lost quite a bit of balance on my AN side before surgery, although I never felt like I was spinning, just wobbly and had wonky head. I used a cane for the first few weeks after surgery, but looking back I think I might have been able to give it up sooner than I did. I found my balance improved much faster after I did. I began vestibular rehab three weeks post-op and although my insurance company only allowed me 12 sessions (wonderful, aren't they?) it also helped enormously. I continue to exercise with a friend who is a dance teacher (ballet exercises) which also helps. I still have some very minor problems, wonky head for sure, outside and in crowds, especially at the mall, but it's not as bad as it was, and if I turn around or turn a corner too quickly I stumble a little, but have never fallen (actually, I might have in the beginning if not or my cane) I still weave a l when I walk but this has improved too. Like everything else to do with the AN experience, being as active as you can and patience is the key. My doc also told me I would regain 90% of my balance in the first month or two the last 10% takes 6 months to a year. It's easy to get impatient waiting for the last bit to return and doesn't mean your balance will ever be what it was again, just that that is about the most improvement you will probably have. Who knows though, if you work at it, it might improve even more past that time. Anyway, stay positive and have a Happy Thanksgiving!
