I have had Sanexas treatment with injections and it helped,But after time i found the pain is back again with no relief,You have to find treatment that is best for you.I work everyday 7 days a week the doctors have told me to slow down a bit it might help the neuropathy pain.I am thinking stem cell treatments are next still doing research to see if it is safe for small fiber neuropathy. at this point i would drink rattle snake juice if it worked.
