Keep in mind that they seem to be making a distinction between L-carnitine and acetyl-L-carnitine. They are using the latter.
In any case, it appears that carnitine IS suggested for P.N. And after all, nerve cells have mitochondria too, and need to produce energy for their own functions.
Not heard about primrose oil, but maybe I have about the active ingredient in hot peppers (i.e., capsaicinoids) where it too is apparently rubbed on the feet. This suggests a couple of things:
1) that the pain is indeed located close to the surface -- on the skin, rather than deeper in the foot -- as I also picture that from reading the hyperlinked study's text
2) the mechanism of therapeutic action for either or both (primrose oil or peppers) may be in providing for "competing traffic" along the nerves. I have read that this is why rubbing the area that is delivering pain works. Say if you stump your toe. You are tying up the nerves with the sensation of the rubbing action rather than getting the full pain of the injury. Both signals do not go through together very well in full strength.
Since reading this study, I take 1,500 mg of each version of carnitine and plan to continue beyond the 33 month length of the study. There is no doubt that I have had a lot of improvement with P.N., but who is to say that it would not have occurred at the same rate of recovery anyway? But I guess I am not willing to take that chance.
I sympathize with your plight and sure hope it improves.
In a more perfect world, there is no doubt that you would get compensation for your injuries.
