"Well within a couple hours my feet, ankles, legs had random hot sensations, pin/needles, vibrations. Pretty uncomfortable, not screamly painful but enough to really bother me. Also for up to a week after that my feet were more painful, and only calmed down a couple days ago"

yes i think most P/N sufferers have the above after exertion. I certainly do
You certainly are showing classic symptoms. My first indication was night cramps in my feet for 6 months then a numb patch on sole of the foot then toes and now to the ankles burning etc. It really sneaks up on you...

"'ve dropped off the Gabapentin after a month, 900mg a day wasnt doing much except making me spacey. I started Amitrityline, hoping that helps with pain and depression"

You should be on low dose amitrityline 25mg or less, apparently not enough for depression but perfect for pain. Im taking it and it really is a magic bullet however after a few weeks im finding the side effects even worse than Lyrica
