Botox treatment for chiari pain management

Hi everyone,
My dear sister in law is struggling with chiari pain daily and I am trying to help her with her doctoring. She is in the process of getting approved for Botox injections for help with pain management. I was wondering if anyone has had this procedure and if so could you message me with your dr name clinic and phone number? I am trying to put together a file of others who have had this for chiari pain treatment for when we go to the neurologist next week. You don’t need to leave your personal info just the dr or clinic name would be great. Thanks so much.
