I'm 70 years old and first started experiencing PN (small fiber, idiopathic, they tell me) symptoms about 15 years ago. Over the years it progressed very gradually and never got to a point where it troubled me too badly.

About 4 months ago I underwent some stress and have been suffering from severe insomnia ever since. During this time my PN symptoms have increased dramatically. I suspose there's a relation there but I was wondering if anyone had any data or thoughts about that. Can the nervous system become inflamed? That's how it feels. Will this improve once I start sleeping again?

A second question has to do with walking. I try to stay fairly active and take long walks lately (even more so lately as a means of curbing the insomnia). The extensive walking however seems to further agravate the PN symptoms. I am noticing more pain, numbness and a spreading of the symptoms up the side and top of my feet. Anyone have any insights?

Thanks,
Terry
