You mentioned that one of the main causes of Stocking and Glove Neuropathy is a a B-12 deficiency. You, (posting list member knows who he is) also stated that he has no vitamin deficiency. Actually a vitamin B-12 deficiency is more common than most know. First, B-12 does not belong to the water soluble category of B vitamins. It is technically not a vitamin at all but a mineral (cobalt). The cobalt (cobalicimin) molecule is so large that the human body only absorbs this mineral 1) in the presence of something the body produces called intrinsic factor 2) that the tiny absorbtion site in the large intestine is not mucus coated or damaged in some way. The spot where this mineral can be absorbed is only the size of a half dollar coin and then only in the presence of the body's self produced intrinsic factor.
When doctors ask about your diet and discover that you eat well so therefore probably have no b-12 deficiency, they may have made an incorrect assumption. A blood test is needed. Even then, people have reported excellent improvement in body function with a single injection of B-12. It's so cheap that a needle and a dose should cost less than a dollar. You can get it for a few bucks at any Mexican pharmacy, You can bribe some pharmacies to sell it to you in the U.S. You can purchase it mail order (sometimes only vet grade.) You can convince your doctor to give you a shot. One shot, even if you are deficient might last you five years. The package insert states no known negative effect other than anaphalactic shock (rare ... very rare).
Next time you are in Tijuana, walk into any pharmacy, ask for B-12, pay your 5 bucks and lean over the table behind the curtain. Watch them use a disposable needle freshly unwrapped. They always tap the needle while held upright and squirt the first drop out before injecting intra muscle. Any military medic knows the routine.
