I would like to know your blood test result for the B12. Often doctors tell patients "normal" or give monthly shots, when another way to take care of the problem exists.

For example, if you have the MTHFR mutation (which over 10% of people in USA have), you will not be able to methylate B12 from the shots containing cyano form. Also you will be unable to methylate folic acid to methylfolate.

Methylcobalamin (the active form for B12) is the cofactor for synthesizing melatonin (sleep hormone) in the brain. If you do not have enough, you won't be sleeping well.

So right there, if you "need" shots, you may have more wrong than your doctor understands.

Taking ORAL methylcobalamin daily in high doses is the best way to insure your B12 is optimum.
This is our B12 information thread:

Niacin does cause a buildup of bradykinin in the skin which can give burning and zapping sensations. This can be blocked by taking one adult aspirin an hour before the niacin.

The supplements shown over the years to help diabetics are:

Lipoic acid
Benfotiamine
Acetyl carnitine.

Diabetics also lose magnesium thru the urine, so taking that is also helpful.

Here is my Supplement thread:

We have a link to PubMed on each page here at the top right.
You can search things there with keywords "diabetic"
To do drugs use the generic name (not the brand name) and
for supplements, do the name + diabetic neuropathy.

Alpha lipoic acid (the older type) and r-lipoic acid (the newer type allowing for lower doses) are both on PubMed along with
Benfotiamine and acetyl carnitine.

All three of these may be very helpful for you.

If you are on a statin drug...??? most diabetics are... you are going to run into problems. Firstly you need quality high dose CoQ-10 with absorption enhancements, and you may not respond to supplements I've listed above the same way a person not taking statins will. Statin drugs can cause mitochondrial damage in the cells, and result in neuropathies for some people. Continuing to use them, will continue the damage if it has already started.

Antibiotics Cipro, Levaquin, and Avelox also have a potential for nerve damage. Very little is known about fixing it once it occurs.
