Hi Sydney, i just realised that you had started a brand new thread

This is a fantastic forum with plenty of very smart and caring people who although are suffering themselves, are quick to lend a hand to anyone that is in need, and it is good to vent and let out some of your frustrations, as most here really do understand.

Pn can spread, in my case PN started in the balls of my feet then spread all over the feet and started to climb my legs up to my knees, then stopped and luckily i was able to reverse the damage.
Have you had any PN tests ? like nerve conduction test, EMG, thermal, vibration tests, b12 levels, etc., those freezing feet sounds like small nerve damage, i have read plenty of people here talk of freezing feet or to the other extreem, burning feet in whatever differant seasons of the year.
Never know whats around the corner, i hope that you will be able to drive again and come over here again to see your friends again.
I am sure others will be along shortly.
all the best
Brian
