Andrea,
I have had balance problems for a while now. I had 4 bier blocks years ago but didn't have any problems. (god bless allison for being able to go through with the block). My balance problems started 2 yrs. ago. I think that my leg is not strong enough for me to walk without a problem. I have fallen many times from losing my balance. I now use crutches for safety issuses. I hope that you get the answers you need. I always think of Ali and am so sad that at her age she has to go through this. Give her my best.
