I haven’t tried stem cells, as I just can’t find any research that shows it has any great affect. I still think there is a lot of hope for future success, I just don’t think the science is there yet. I have been doing a great vitamin protocol that has seem to hault any progression, and will start intraneural facilitation at Loma Linda hospital Monday in hopes of further healing the nerves. Also to answer the question I don’t believe stem cells are covered by insurance yet.
