Have you ascertained the etiology of the peripheral neuropathy, e.g., post-traumatic, metabolic, toxic, etc.?
My suggestions are as follows for the treatment of peripheral neuropathy:
ARA-290 0.5 ml SQ qday (or BID, depending upon severity) for 6 to 8 weeks and then reassess
TB4 0.25 ml SQ qday (or BID, depending upon severity) for 6 to 8 weeks and then reassess
Astaxanthol 3 capsules BID for 12 weeks and then reassess (from PGL, 800-527-9512)
R-Lipoic Acid 600 mg BID for 12 weeks and then reassess
ProdromeGlia 4 ml qPM with evening meal for 12 weeks and then reassess
Good luck, Mitch
