Hi, Carmen,
I had my surgery in Jan, 2004 , left side 6cm+ , also had left side facial paralysis. I stayed in hospital for five weeks due to different complications and uncontrollable pain, by the time I left, I had three other surgeries beside the brain surgery. During my hospital stay, the doctors tried all kinds of pain medication none of them worked, I am in pain constantly. However, ever since I left hospital, I never had any pain again, what a relief! So my suggestion is that stay away from hospital ( living hell to me ), change your enviorment might also ease your pain ( in my case, I went home the pain was gone ). Regarding the balance issue you have , there are no easy solution, you might have to do phyisical theraphy for a few months. In my case, I had PT for about half year, Now, I am almost back to normal. I guess the most important thing is don't give up hope, time will heal everything for you eventually. Good luck in your recovery.
