Hi and welcome, I know my friend who says her dx is idiopathic, has gotten nice improvement since taking grape seed extract now for 3-4 yrs...she is off neurontin and now talks about grape seed ex to many of her friends, she has her adult daughter on it too for general overall health. This friend thinks her nerve issues are from taking statins for 30 yrs and could be so as I know of the damage from those statins, but I think too there is diabetes involved, as she said once she was borderline...

I'm head to 20 yrs on OPC'S, which for me are pycnogenol and then a year later grape seed extract, so my prime OPC is grape seed ex.

I can't say enough about these OPC's and have posts in other areas here. Do your research. I deal with femoral nerve damage from hip replacement and getting some relief with a couple nerve supps I've discussed here lately....inosine and sphingolin.
