Thank you John,

This is a starting point. Get those blood levels of D and B12, , and did you have carnitine measured? Please get your number results for the B12 especially, because you could still be low and not know it.

The medication you take depletes carnitine.

Carnitine is one supplement used for some PNs, that are drug induced. Chemo drugs often deplete carnitine as well, and this is due to mitochondria damage.

This is our mitchondrial information thread:

Damage to the mitochondria over time stops the cells from producing energy. The nervous system seems very prone to this, and damage to it leads to all sorts of symptoms.

Mito damage is now thought to be a major cause of PNs but that is still in the research arena.

Do you eat foods that supply enough magnesium daily? If not doing that is very helpful, or a supplement (any type except OXIDE form which is not absorbed). Dose magnesium to start at 1/2 the RDA which is about 200mg elemental. Diabetics lose magnesium in the urine more so than non-diabetics, so looking into that would be helpful for you.

Here is my magnesium thread:
