The oregon state link above talks about sphingomylein...well, there is a huge connection then with the Sphingolin I took for 3 months along with Inosine that got rid of the Burn issue I talked about from hip surgery Nerve Damage.

I'm far from scientific but do have trust in naturopaths more than MD's....I have a post about these two supps I took on the suggestion of a naturopath. The burn issue is basically gone on my thigh.
This Sphingolin is suggested for MS patients also.
