Very early sensorimotor polyneuropathy, what can be done to reverse progression?

Visit specialist: You likely has NCS/EMG. I advise to visit with a neurologist and assure that required labs are performed, so if was reversible cause identified it can be cured.

Agree with Dr. M: Consulting a neurologist is important. In the mean time you may take multivitamins including vitamin B12.

Address the cause!: Western medicine is not that great at dealing with polyneuropathy but an integrative/functional medicine Dr. such as David Steenblock in your area can help. This may be related to environmental toxins and/or chronic infections and nutrient deficiencies. Innovative treatments like microcurrent, hyperbaric oxygen and palmitoylethanolamide often help- see http://tinyurl.com/yytth72s
