Are you talking stem cell therapy....using stem cells derived form your own fat tissue that are re-injected into damaged nerves in hope to initiate regeneration? I had this procedure done at the New England Center for regenerative medicine in MA.
I had it done in April 2015 and December 2015. To date, I do not feel my peripheral nerves are any different. I did not have pain, so I do not know if it might help with that. I had it done hoping for peripheral nerve regeneration. My symptoms are weakness/calf atrophy.
