Hi Fred!
I used to have pretty bad numbness in my feet and learning from your experiences i almost reveresed the damage few years ago.
I got sloppy and it's been awhile since i religiously took them.
I am now experiencing numb patches on my right toe and index finger on my right hand. And my whole righ arm feels like it's asleep.
I met a GP today that said B12 related neuropathy is symmetrical so this can't be it. I really doubt what he said. Was your neuropathy symmetrical by any chance?
/thank u so much in advance
Hi Jaz,
Sorry to hear of your perhaps relapse. Neuropathies are tricky things. The very first part of the problem is what does "B12 deficiency" actually mean. In the USA it basically depends on getting your serum level appallingly low (170 pg/ml) where serious damage is already likely. It also has a very short list of possible or probable deficiency symptoms. The thing the test absolutely can't tell you is whether a person has sufficiency. A study on peripheral neuropathies was done in the UK maybe a decade or so ago. They did something radical. While they took all the usual tests, admission into the study was only by symptoms and in this study the symptoms were symptoms of peripheral neuropathy, not one or two symptoms, any of them, many of them. And there were no test "endpoints" being aimed for. They were going for percentage of people have an amount of improvement by the end of the period of the study. So the people in the study had an typical serum level of 700+ pg/ml which is defined as so ample that they shouldn't be allowed in the study becasue how could there be improvement? Of those 63% of participants who had improvement, some had levels even higher than 1500 pg/ml to start out.
So in this measurement of serum level the incredibly false assumption is made that there is one number that represents the whole body. Instead there are multiple compartments. For the simplest schema that is worth anything, there are at least 4 compartments All for of them are reasonably independent, some can be high and some low and nobody knows why. For that matter, for functional healing there are at least 8 compartments (epithelial, muscles, with separate nutritional combinations needed for healing tissues in that compartment.
- MeCbl - Body
- MeCbl - Cerebral spinal fluid and Brain-cord
- AdoCbl - Body
- AdoCbl - Cerebral spinal fluid and Brain-cord
So for instance, non symmetrical neuropathies with CNS cbl not measured and body serum CBL above 170 pg/ml it could be MS because MS requires it to NOT be B12 deficiency (elimination). It doesn't matter at all that the person can have terribly low cerebral spinal CBL with elevated CSF Homocysteine and it doesn't matter for MS becasue of the wacky ignoring of the CSF CBL deficiency, they don't even define it, as if it doesn't exist, despite being common to FMS, CFS,MS, Parkinsons, SupraNuclear Palsy, ALS and other syndromes and/or diseases.
Healing of nerves does not depend on the damage being caused by B12 and folate deficiencies in the first place. So studies of purposely crushed sciatic nerves (in mice) Only MeCbl increased healing of the damaged nerves and appears to also be able to heal some toxic chemical damage to nerves as well. In the Japanese studies with 2.5mg MeCbl injected into the CSF in the cases caused by diabetes, the symptoms had relief as long as the CSF cbl level stayed high. So far the range of duration goes from under three months to over 4 years. That variation in retention of CSF cbl appears to be the cause of a lot of problems for some of us.
So let's look at some of the reasons now. I have been regaining skin sensation for a couple of years at the same time as my muscles in my feet are going quite numb and painful in various areas. Copper can cause "Subacute Combined Degeneration" type lesions" along with mood disorders and a dozen or so symptoms of failed methylation. These symptoms can be caused by lack of AdoCbl, MeCbl, L-methylfolate, L-carnitine (ALCAR or Fumarate determined genetically it appears), SAM-e, Biotin, d-ribose, other B-vitamins (too much or too little), copper, Boron (probably), manganese (possibly), molybdenum (possibly), and some others (almost certainly). They only respond in the correct order. So if the deadlock quartet are adequatl;y taken, up to a few hundred symptoms have gone away but a few possible methylation failure type symptoms are there chances are it is a trace mineral.
In peripheral neuropathy and the absence of other methylation affected items, a common cause is circulation problems which can cause distal die-off of the nerve for instance. These are often one sides but can certainly happen that it happen on both sides. It's like shingles. They say "it isn't shingles" if it is bi-lateral symmetrical. My partner had bi-lateral symmetrical shingles, twice. Something like a 5% probability, so it is not terribly rare, just not the 95% case. You could use a more thorough neurological exam to determine how much is central and how much is peripheral as it is quite possible to have both at the same kind and to the casual examiner, not a lot of difference. There can be traumatic damage as well as biochemical damage.
I had more bi-lateral symptoms than I had bi-lateral symmetrical symptoms. I also have had one sided damaged nerves including demyelination. 10 years ago I had foot drop before the B12 and folate healed it. Now it has been worsening for several years becasue of copper deficiency, not the same going in, but may end up with the same problems as copper deficiency goes after upper motor neurons. Good luck.
