question: Helo sir, My dad is suffering from hemifacial spasm from past 10 years. After consulting the doctor, the doctor advised Botox injections and gave some pills oXETOL, but we do not want to go for Botox because it is very costly for us and it is not a permanent cure. I have read on net that MVD surgery is a permanent cure and there is a risk of loosing the sense of hearing. I also read of catalyst therapy. which one would you think is beneficial? We are staying Bangalore, is catalyst therapy available in Bangalore?
