For me it seems to have stabilized. My PCP who is also a vein specialist is finally getting around to maybe doing something about it. Funny thing I've noticed is that [in spite of or because of compression stockings] my left lower leg fills up with fluid and swells and feels hard to the touch. At night while asleep the fluid drains back out. The issue is more prevalent with the left leg than it is wih the right leg.

I believe that I have both PN and diabetic neuropathy. I had pain in my left side chest and it was sensitive to to touch from clothing. Also I used to itch like mad all over esp. later in the day. Both the itching and chest pain have gone away since I started using PreGabalin. Unfortunately being pre-diabetic caused some nerve damage in my right lower leg resulting in foot drop.
Nothing to do with the lower back pain IMO.
