Nice nic lol. Okay this may help you as well.
I have the exact same symptoms that developed over time along with PN being complete muscle weakness and lots of pain in the knees, ankles (only when I walk) and impossible do walk down stairs without grabbing a railing. Basically I should have had a cane just to leave the house.

My doc put me on Diclofenic and from the very first dose it all went away and I take 2 a day for the last 12 months and I tried stopping and all the symptoms came straight back. Its an anti inflammatory drug that may take care of the inflamed part of the PN that maybe distorts the signals to your leg muscles??. Those pills saved my life and Im not kidding
