Thanks and good luck with what ever you choose. Tomorrow is my apt and my doc there is a lot written about and I know someone who got the surgery from him. He deals a lot with rsd. I am concerned about the batter pack cause I already have back issues and like you am slim.I think if I am happy with my treatment and he is my 4th pain doc at major places anyhow and the procedure I am going to make a blog so that other patients can get feedback. Like you knowing someone who has been to that doc can really help to make a good choice and feel more comfortable. Good luck and thanks
